Given numbers are 678,434,541,620

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

The LCM of 678,434,541,620 is 795951660.

Find LCM of 678,434,541,620 with Prime Factorization

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

2 x 31 x 339 x 7 x 541 x 10 = 795951660

Therefore, the lowest common multiple of 678,434,541,620 is 795951660.

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.

678 x 434 x 541 x 620 = 98698005840

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.

678 : 1, 2, 3, 6, 113, 226, 339, 678

434 : 1, 2, 7, 14, 31, 62, 217, 434

541 : 1, 541

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,434,541,620, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

434:2x 7x 31

541:541

620:2x 2x 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.

2x 2x 31 = 124

Therefore, the value for common factors is 124.

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 = 98698005840/(1x124)

LCM = 98698005840/124

LCM = 795951660

Thus, we can understand that the LCM of 678,434,541,620 is 795951660.
