Given numbers are 751,392,766,393,645

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

The LCM of 751,392,766,393,645 is 9526991731320.

Find LCM of 751,392,766,393,645 with Prime Factorization

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

2 x 3 x 751 x 196 x 383 x 131 x 215 = 9526991731320

Therefore, the lowest common multiple of 751,392,766,393,645 is 9526991731320.

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.

751 x 392 x 766 x 393 x 645 = 57161950387920

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.

751 : 1, 751

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

766 : 1, 2, 383, 766

393 : 1, 3, 131, 393

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 751,392,766,393,645, is 1.

Now, the common factors can be found like this.

751:751

392:2x 2x 2x 7x 7

766:2x 383

393:3x 131

645:3x 5x 43

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 57161950387920/(1x6)

LCM = 57161950387920/6

LCM = 9526991731320

Thus, we can understand that the LCM of 751,392,766,393,645 is 9526991731320.
