Write down the factors of each number. Hence 3 = 1,3 4 = 1,2,2,4 5 = 1, 5, 6 = 1,2,3,6 7 = 1, 7 Hence 1, is common to all number. 2, is common to two numbers 3, is common to two numbers 5 is common to one number 7 is common to one number. Hence 1 x 2 x 3 x 5 x 7 = 210 the LCM.
There are infinitely many common multiples of 3, 5 and 7, each one 105 larger than the previous one. Or to put it another way: the common multiples of 3, 5 and 7 are the multiples of their lowest common multiple which is 105. ie their common multiples are all the multiples of 105, of which there is no end - there is an infinite number of multiples of 105 (or any other number [except zero]).
Assuming you mean the whole number 5 and the whole number 7, then the common denominator would be 1, as 5/1=5 and 7/1=7. The GCF of 5 and 7 is 1. The LCM of 5 and 7 is 35. If you are talking about common denominators, the LCM is applicable.
The least common multiple of 4 , 7 , 5 , 3 = 420

The least common multiple of 3, 5, and 7 is 105.This is the first number that each of these numbers have in common when finding the multiples of each number. You begin by taking each number and multiplying the number by 1, 2, 3, 4, 5, etc. until you come up with a number that is common to each of the numbers (3,5 and 7). In this case, the first number that the three numbers had in common happened to be 105. The number 3 had to be multiplied 35 times (35x3=105); The number 5 had to be multiplied 21 times (21x5=105); and the number 7 had to be multiplied 15 times to have a number in common with the other two numbers (15x7=105).
There are infinitely many common multiples of 3, 5 and 7, each one 105 larger than the previous one. Or to put it another way: the common multiples of 3, 5 and 7 are the multiples of their lowest common multiple which is 105. ie their common multiples are all the multiples of 105, of which there is no end - there is an infinite number of multiples of 105 (or any other number [except zero]).
There is only one common factor of 5, 3, 7: 1
Assuming you mean the whole number 5 and the whole number 7, then the common denominator would be 1, as 5/1=5 and 7/1=7. The GCF of 5 and 7 is 1. The LCM of 5 and 7 is 35. If you are talking about common denominators, the LCM is applicable.
The least common multiple of 4 , 7 , 5 , 3 = 420
The least common multiple of 4 , 5 , 3 , 7 = 420
Well, darling, the lowest common multiple of 2, 3, 5, and 7 is 210. Why? Because that's the smallest number that all those little divas can divide into without any drama. So, there you have it, 210 is the winner of the "Lowest Common Multiple" pageant.
735/3=245/7=35/7=5 2625/3=875/7=125/5=25/5=5 ring the factors in common which are 3*7*5 =105 highest common factor
Factoring each number into product of primes: 5=1 x 5 7 = 1 x 7 9 = 3 x 3, 1 x 9 The number 5 is a factor of 5 only; Include 5 in answer The number 7 is a factor of 7 only; Include 7 in answer The number 3 is a factor twice of 9; Include 3x3 in answer Therefore, LCM(5,7,9) = 3 x 3 x 5 x 7 = 315 Additional content regarding LCM may be referenced at http://www.math.info/Arithmetic/LCM
The first common multiple of 3 4 5 and 7 is 420.
The common denominator here is 35. 3/5+5/7 is 21/35+25/35. This is 46/35 or 1 and 11/35.
