Given numbers are 668,420,107,611,715

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 668,420,107,611,715 is 50440970580.

Find LCM of 668,420,107,611,715 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 5 x 13 x 167 x 21 x 107 x 47 x 11 = 50440970580

Therefore, the lowest common multiple of 668,420,107,611,715 is 50440970580.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

668 x 420 x 107 x 611 x 715 = 13114652350800

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

668 : 1, 2, 4, 167, 334, 668

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

107 : 1, 107

611 : 1, 13, 47, 611

715 : 1, 5, 11, 13, 55, 65, 143, 715

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,420,107,611,715, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

420:2x 2x 3x 5x 7

107:107

611:13x 47

715:5x 11x 13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 5x 13 = 260

Therefore, the value for common factors is 260.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 13114652350800/(1x260)

LCM = 13114652350800/260

LCM = 50440970580

Thus, we can understand that the LCM of 668,420,107,611,715 is 50440970580.
