1 is the least common factor of the number 2, number 4 and number 7. 28 is the least common multiple of the number 2, number 4 and 7.
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.
4 5/7
4/4*5*7 = 1*5*7 = 5*7 = 35
The least common multiple of 4 , 7 , 5 , 3 = 420
The Least Common Multiple (LCM) for 4 5 7 is 140.
1 is the least common factor of the number 2, number 4 and number 7. 28 is the least common multiple of the number 2, number 4 and 7.
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.
The smallest number which is a common multiple of both 7 and 4 is 28.
4 5/7
4/4*5*7 = 1*5*7 = 5*7 = 35
The least common multiple of 4 , 7 , 5 , 3 = 420
The least common multiple of 4 , 5 , 3 , 7 = 420
It is: 4+7+5+4+5 = 25/5 = 5 which is the average number
To find the least 4-digit number divisible by 2, 3, 4, 5, 6, and 7, we need to find the least common multiple (LCM) of these numbers. The LCM of 2, 3, 4, 5, 6, and 7 is 420. The smallest 4-digit number divisible by 420 is 1050. Therefore, 1050 is the least 4-digit number divisible by 2, 3, 4, 5, 6, and 7.
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.
28 The LCM (least common multiple) is the number which shares a multiple of two or more numbers. Often, the LCM of the number is simply the two numbers multiplied together (4 & 7, 3 & 5, 3 & 4), but sometimes they have a common multiple of a lower value (6 & 4, 5 & 10, 3 & 9).
