Given numbers are 421,702,556,862

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

The LCM of 421,702,556,862 is 35411251356.

Find LCM of 421,702,556,862 with Prime Factorization

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

2 x 421 x 351 x 278 x 431 = 35411251356

Therefore, the lowest common multiple of 421,702,556,862 is 35411251356.

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.

421 x 702 x 556 x 862 = 141645005424

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.

421 : 1, 421

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

556 : 1, 2, 4, 139, 278, 556

862 : 1, 2, 431, 862

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,702,556,862, is 1.

Now, the common factors can be found like this.

421:421

702:2x 3x 3x 3x 13

556:2x 2x 139

862:2x 431

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 141645005424/(1x4)

LCM = 141645005424/4

LCM = 35411251356

Thus, we can understand that the LCM of 421,702,556,862 is 35411251356.
