Given numbers are 651,916,989,646

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

The LCM of 651,916,989,646 is 190491357252.

Find LCM of 651,916,989,646 with Prime Factorization

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

2 x 651 x 458 x 989 x 323 = 190491357252

Therefore, the lowest common multiple of 651,916,989,646 is 190491357252.

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.

651 x 916 x 989 x 646 = 380982714504

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.

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

916 : 1, 2, 4, 229, 458, 916

989 : 1, 23, 43, 989

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 651,916,989,646, is 1.

Now, the common factors can be found like this.

651:3x 7x 31

916:2x 2x 229

989:23x 43

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 = 380982714504/(1x2)

LCM = 380982714504/2

LCM = 190491357252

Thus, we can understand that the LCM of 651,916,989,646 is 190491357252.
