Given numbers are 857,763,436,155

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

The LCM of 857,763,436,155 is 405412420.

Find LCM of 857,763,436,155 with Prime Factorization

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

109 x 857 x 7 x 4 x 155 = 405412420

Therefore, the lowest common multiple of 857,763,436,155 is 405412420.

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.

857 x 763 x 436 x 155 = 44189953780

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.

857 : 1, 857

763 : 1, 7, 109, 763

436 : 1, 2, 4, 109, 218, 436

155 : 1, 5, 31, 155

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 857,763,436,155, is 1.

Now, the common factors can be found like this.

857:857

763:7x 109

436:2x 2x 109

155:5x 31

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

109 = 109

Therefore, the value for common factors is 109.

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 = 44189953780/(1x109)

LCM = 44189953780/109

LCM = 405412420

Thus, we can understand that the LCM of 857,763,436,155 is 405412420.
