Calculate the LCM of 665,143,946,730

Given numbers are 665,143,946,730

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

The LCM of 665,143,946,730 is 597006410.

Find LCM of 665,143,946,730 with Prime Factorization


2 665, 143, 946, 730
5 665, 143, 473, 365
11 133, 143, 473, 73
133, 13, 43, 73

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

2 x 5 x 11 x 133 x 13 x 43 x 73 = 597006410

Therefore, the lowest common multiple of 665,143,946,730 is 597006410.

LCM Formula to Find Lowest Common Multiple of 665,143,946,730

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.

665 x 143 x 946 x 730 = 65670705100

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.

665 : 1, 5, 7, 19, 35, 95, 133, 665

143 : 1, 11, 13, 143

946 : 1, 2, 11, 22, 43, 86, 473, 946

730 : 1, 2, 5, 10, 73, 146, 365, 730

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,143,946,730, is 1.

Now, the common factors can be found like this.

665:5x 7x 19

143:11x 13

946:2x 11x 43

730:2x 5x 73

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

2x 5x 11 = 110

Therefore, the value for common factors is 110.

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 = 65670705100/(1x110)

LCM = 65670705100/110

LCM = 597006410

Thus, we can understand that the LCM of 665,143,946,730 is 597006410.
