You need at least two numbers to find something in common, but I'll save you the trouble. The least common factor of any set of positive integers is 1.
The factors of 10 are 1, 2, 5, and 10. The factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70. The common factors of 10 and 70 are 1, 2, 5, and 10. Therefore, the least common factor (the smallest common factor) is 1.
You need at least two numbers to find something in common.
The LCM is the product of the two divided by the GCF Factors of 15 are [3 5] Factors of 70 are [2 5 7] Common factor is [5] (15 * 70) / 5 = 210 ■
the least common factors that 165 and 330 share are 1,5,14,35, and 70.
The least common factor of 140 and 210 is 1. I think you meant the greatest common factor which would be 70.
Least common multiple of 7 and 70 is 70.
The factors of 21 are 1,3,7, and 21. The factors of 70 are 1,2,5,7,14,35, and 70 The common factors of 21 and 70 are 1 and 7.
There cannot be a common factor (GCF) of just one number. To be common there need to be at least two numbers.
The Least Common Multiple (LCM) for 2 70 is 70.
The common factors of 44 and 70 are: 1 and 2
Since 35 is a factor of 70, all of its factors are common.
The LCM of 5 and 14 is 70, which is the multiple of the combined prime factors of both numbers (2 x 5 x 7).7070
