Calculate the LCM of 646,646,748,707

Given numbers are 646,646,748,707

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

The LCM of 646,646,748,707 is 10047884.

Find LCM of 646,646,748,707 with Prime Factorization


2 646, 646, 748, 707
17 323, 323, 374, 707
19 19, 19, 22, 707
1, 1, 22, 707

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

2 x 17 x 19 x 1 x 1 x 22 x 707 = 10047884

Therefore, the lowest common multiple of 646,646,748,707 is 10047884.

LCM Formula to Find Lowest Common Multiple of 646,646,748,707

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.

646 x 646 x 748 x 707 = 220691724176

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.

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

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

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

707 : 1, 7, 101, 707

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,646,748,707, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

646:2x 17x 19

748:2x 2x 11x 17

707:7x 101

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 17x 17x 19 = 21964

Therefore, the value for common factors is 21964.

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 = 220691724176/(1x21964)

LCM = 220691724176/21964

LCM = 10047884

Thus, we can understand that the LCM of 646,646,748,707 is 10047884.
