Given numbers are 520,521,671,129,978

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

The LCM of 520,521,671,129,978 is 3822441977640.

Find LCM of 520,521,671,129,978 with Prime Factorization

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

2 x 3 x 260 x 521 x 671 x 43 x 163 = 3822441977640

Therefore, the lowest common multiple of 520,521,671,129,978 is 3822441977640.

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.

520 x 521 x 671 x 129 x 978 = 22934651865840

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.

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

521 : 1, 521

671 : 1, 11, 61, 671

129 : 1, 3, 43, 129

978 : 1, 2, 3, 6, 163, 326, 489, 978

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,521,671,129,978, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

521:521

671:11x 61

129:3x 43

978:2x 3x 163

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 22934651865840/(1x6)

LCM = 22934651865840/6

LCM = 3822441977640

Thus, we can understand that the LCM of 520,521,671,129,978 is 3822441977640.
