Calculate the LCM of 665,478,419,132

Given numbers are 665,478,419,132

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

The LCM of 665,478,419,132 is 8790376980.

Find LCM of 665,478,419,132 with Prime Factorization


2 665, 478, 419, 132
665, 239, 419, 66

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

2 x 665 x 239 x 419 x 66 = 8790376980

Therefore, the lowest common multiple of 665,478,419,132 is 8790376980.

LCM Formula to Find Lowest Common Multiple of 665,478,419,132

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 478 x 419 x 132 = 17580753960

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

478 : 1, 2, 239, 478

419 : 1, 419

132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,478,419,132, is 1.

Now, the common factors can be found like this.

665:5x 7x 19

478:2x 239

419:419

132:2x 2x 3x 11

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 = 17580753960/(1x2)

LCM = 17580753960/2

LCM = 8790376980

Thus, we can understand that the LCM of 665,478,419,132 is 8790376980.
