Given numbers are 393,639,121,262

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

The LCM of 393,639,121,262 is 20257578.

Find LCM of 393,639,121,262 with Prime Factorization

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

3 x 131 x 1 x 213 x 121 x 2 = 20257578

Therefore, the lowest common multiple of 393,639,121,262 is 20257578.

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.

393 x 639 x 121 x 262 = 7961228154

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.

393 : 1, 3, 131, 393

639 : 1, 3, 9, 71, 213, 639

121 : 1, 11, 121

262 : 1, 2, 131, 262

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,639,121,262, is 1.

Now, the common factors can be found like this.

393:3x 131

639:3x 3x 71

121:11x 11

262:2x 131

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

3x 131 = 393

Therefore, the value for common factors is 393.

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 = 7961228154/(1x393)

LCM = 7961228154/393

LCM = 20257578

Thus, we can understand that the LCM of 393,639,121,262 is 20257578.
