LCM of:

Calculate the LCM of 749,417,966,660

Given numbers are 749,417,966,660

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

The LCM of 749,417,966,660 is 1580404980.

Find LCM of 749,417,966,660 with Prime Factorization


2 749, 417, 966, 660
3 749, 417, 483, 330
7 749, 139, 161, 110
107, 139, 23, 110

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

2 x 3 x 7 x 107 x 139 x 23 x 110 = 1580404980

Therefore, the lowest common multiple of 749,417,966,660 is 1580404980.

LCM Formula to Find Lowest Common Multiple of 749,417,966,660

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.

749 x 417 x 966 x 660 = 199131027480

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.

749 : 1, 7, 107, 749

417 : 1, 3, 139, 417

966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,417,966,660, is 1.

Now, the common factors can be found like this.

749:7x 107

417:3x 139

966:2x 3x 7x 23

660:2x 2x 3x 5x 11

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

2x 3x 3x 7 = 126

Therefore, the value for common factors is 126.

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 = 199131027480/(1x126)

LCM = 199131027480/126

LCM = 1580404980

Thus, we can understand that the LCM of 749,417,966,660 is 1580404980.
