Given numbers are 620,740,344,158,521

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

The LCM of 620,740,344,158,521 is 81200121560.

Find LCM of 620,740,344,158,521 with Prime Factorization

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

2 x 2 x 5 x 31 x 37 x 86 x 79 x 521 = 81200121560

Therefore, the lowest common multiple of 620,740,344,158,521 is 81200121560.

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.

620 x 740 x 344 x 158 x 521 = 12992019449600

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

344 : 1, 2, 4, 8, 43, 86, 172, 344

158 : 1, 2, 79, 158

521 : 1, 521

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,740,344,158,521, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

740:2x 2x 5x 37

344:2x 2x 2x 43

158:2x 79

521:521

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 2x 2x 2x 5 = 160

Therefore, the value for common factors is 160.

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 = 12992019449600/(1x160)

LCM = 12992019449600/160

LCM = 81200121560

Thus, we can understand that the LCM of 620,740,344,158,521 is 81200121560.
