Given numbers are 671,302,319,780

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

The LCM of 671,302,319,780 is 2291881020.

Find LCM of 671,302,319,780 with Prime Factorization

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

2 x 11 x 61 x 151 x 29 x 390 = 2291881020

Therefore, the lowest common multiple of 671,302,319,780 is 2291881020.

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.

671 x 302 x 319 x 780 = 50421382440

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.

671 : 1, 11, 61, 671

302 : 1, 2, 151, 302

319 : 1, 11, 29, 319

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,302,319,780, is 1.

Now, the common factors can be found like this.

671:11x 61

302:2x 151

319:11x 29

780:2x 2x 3x 5x 13

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 50421382440/(1x22)

LCM = 50421382440/22

LCM = 2291881020

Thus, we can understand that the LCM of 671,302,319,780 is 2291881020.
