Find the least number that should be subtracted from 1000 so that 30 divides the difference exactly?
which least number should be subtracted from 1000 so that 30 divides the difference exactly
How do you solve a prime number?
to answer a prime number you must find a number that goes into it and that divides by itself :)
How do you find the least common multiple 35?
Not possible. The LCM (least common multiple) is the smallest positive whole number exactly divisible by two or more whole numbers.
When you divide a whole number by a fraction with a numerator of 1 explain how you can find a quotient?
if your problem is a number with 1 as the numerator the quotient is the bottom # 1 _ 5 5 is the quotient.
What is the GCF of 458 and 70?
Answer: 2Solution: The greatest common factor of two numbers is defined as the largest number that divides both numbers into whole numbers (i.e. divides the numbers evenly).The easiest way to find the G.C.F. in this case is to begin by listing the factors of the smaller number:Factors of 70: 70, 35, 14, 10, 7, 5, 2, 1See if 70 divides 458 evenly (it does not), then 35 (again, it does not), and so on...until we find a factor of 70 that is also a factor of 458. We find that 2 is the largest such number.
How do i find the product and identify the whole number between which the product lies?
You have to carry out the multiplication and thentruncate the answer to find the lower whole number,add 1 to that to find the next whole number.
How do you common factor an expression?
Find a number that evenly divides each term of the expression.
How do you find the real number of a whole number?
A whole number IS a real number so you do not have to do anything.
Find the greatest number which divides 742 and 1162 leaves a remainder of exactly 7 in each case?
This is a slight twist to the normal find the GCF of two numbers. In this case as a remainder of 7 is required, subtracting 7 from each number and then finding the GCF of the resulting numbers will solve the problem: 742 - 7 = 735 1162 - 7 = 1155 GCF of 1155 and 735 (using Euclid's method): 1155 / 735 = 1 r 420 735 / 420 = 1 r 315 420 / 315 = 1 r 105 315 / 105 = 3 r 0 GCF of 735 & 1155 is 105, thus 105 is the greatest number that will divide 742 and 1162 leaving a remainder of exactly 7 each time.
Algorithm to find whether a number is prime or not?
check if 2 divides the Numbercheck if 3 divides the Numbercheck if 5 divides the Number...check if any prime numbers less than the square root of the Number divide the NumberIf any do, the Number is composite; otherwise the Number is prime.This is called the Sieve of Erasthenes.An easy way to check if a prime number divides the Number in base ten (if you don't have a calculator) is to add or subtract 1 or 3 times the prime number to the Number, so that the sum or difference is a multiple of ten (if the prime number isn't 2 or 5). Knock off the zero. If the prime number divides the new number, it also divides the Number; otherwise it doesn't.
How do you find a whole number co-prime?
A whole number is co-prime with another whole number if their GCF is 1.
What does factor mean in math terms?
Factor, in maths terms means "a number that divides into a given number with no remainders". You may be asked to find the "highest common factor" that two number share - this is the "biggest number that divides into both the given numbers, with no remainders".
