Given numbers are 919,651,404,646

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

The LCM of 919,651,404,646 is 78069318348.

Find LCM of 919,651,404,646 with Prime Factorization

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

2 x 919 x 651 x 202 x 323 = 78069318348

Therefore, the lowest common multiple of 919,651,404,646 is 78069318348.

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.

919 x 651 x 404 x 646 = 156138636696

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.

919 : 1, 919

651 : 1, 3, 7, 21, 31, 93, 217, 651

404 : 1, 2, 4, 101, 202, 404

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 919,651,404,646, is 1.

Now, the common factors can be found like this.

919:919

651:3x 7x 31

404:2x 2x 101

646:2x 17x 19

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

2 = 2

Therefore, the value for common factors is 2.

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 = 156138636696/(1x2)

LCM = 156138636696/2

LCM = 78069318348

Thus, we can understand that the LCM of 919,651,404,646 is 78069318348.
