Given numbers are 642,147,968,403,426

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

The LCM of 642,147,968,403,426 is 435652152936.

Find LCM of 642,147,968,403,426 with Prime Factorization

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

2 x 3 x 107 x 49 x 484 x 403 x 71 = 435652152936

Therefore, the lowest common multiple of 642,147,968,403,426 is 435652152936.

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.

642 x 147 x 968 x 403 x 426 = 15683477505696

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.

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

147 : 1, 3, 7, 21, 49, 147

968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968

403 : 1, 13, 31, 403

426 : 1, 2, 3, 6, 71, 142, 213, 426

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,147,968,403,426, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

147:3x 7x 7

968:2x 2x 2x 11x 11

403:13x 31

426:2x 3x 71

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 15683477505696/(1x36)

LCM = 15683477505696/36

LCM = 435652152936

Thus, we can understand that the LCM of 642,147,968,403,426 is 435652152936.
