Given numbers are 688,102,718,611

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

The LCM of 688,102,718,611 is 7696517712.

Find LCM of 688,102,718,611 with Prime Factorization

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

2 x 344 x 51 x 359 x 611 = 7696517712

Therefore, the lowest common multiple of 688,102,718,611 is 7696517712.

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.

688 x 102 x 718 x 611 = 30786070848

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.

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

102 : 1, 2, 3, 6, 17, 34, 51, 102

718 : 1, 2, 359, 718

611 : 1, 13, 47, 611

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,102,718,611, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

102:2x 3x 17

718:2x 359

611:13x 47

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 30786070848/(1x4)

LCM = 30786070848/4

LCM = 7696517712

Thus, we can understand that the LCM of 688,102,718,611 is 7696517712.
