Calculate the LCM of 465,296,665,642

Given numbers are 465,296,665,642

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

The LCM of 465,296,665,642 is 1958754840.

Find LCM of 465,296,665,642 with Prime Factorization


2 465, 296, 665, 642
3 465, 148, 665, 321
5 155, 148, 665, 107
31, 148, 133, 107

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

2 x 3 x 5 x 31 x 148 x 133 x 107 = 1958754840

Therefore, the lowest common multiple of 465,296,665,642 is 1958754840.

LCM Formula to Find Lowest Common Multiple of 465,296,665,642

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.

465 x 296 x 665 x 642 = 58762645200

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.

465 : 1, 3, 5, 15, 31, 93, 155, 465

296 : 1, 2, 4, 8, 37, 74, 148, 296

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

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 465,296,665,642, is 1.

Now, the common factors can be found like this.

465:3x 5x 31

296:2x 2x 2x 37

665:5x 7x 19

642:2x 3x 107

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 5 = 30

Therefore, the value for common factors is 30.

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 = 58762645200/(1x30)

LCM = 58762645200/30

LCM = 1958754840

Thus, we can understand that the LCM of 465,296,665,642 is 1958754840.
