Given numbers are 645,554,786,712

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

The LCM of 645,554,786,712 is 16664441880.

Find LCM of 645,554,786,712 with Prime Factorization

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

2 x 3 x 215 x 277 x 131 x 356 = 16664441880

Therefore, the lowest common multiple of 645,554,786,712 is 16664441880.

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.

645 x 554 x 786 x 712 = 199973302560

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

554 : 1, 2, 277, 554

786 : 1, 2, 3, 6, 131, 262, 393, 786

712 : 1, 2, 4, 8, 89, 178, 356, 712

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,554,786,712, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

554:2x 277

786:2x 3x 131

712:2x 2x 2x 89

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 3 = 12

Therefore, the value for common factors is 12.

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 = 199973302560/(1x12)

LCM = 199973302560/12

LCM = 16664441880

Thus, we can understand that the LCM of 645,554,786,712 is 16664441880.
