Given numbers are 371,678,117,690

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

The LCM of 371,678,117,690 is 1128147930.

Find LCM of 371,678,117,690 with Prime Factorization

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

2 x 3 x 371 x 113 x 39 x 115 = 1128147930

Therefore, the lowest common multiple of 371,678,117,690 is 1128147930.

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.

371 x 678 x 117 x 690 = 20306662740

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.

371 : 1, 7, 53, 371

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

117 : 1, 3, 9, 13, 39, 117

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 371,678,117,690, is 1.

Now, the common factors can be found like this.

371:7x 53

678:2x 3x 113

117:3x 3x 13

690:2x 3x 5x 23

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 20306662740/(1x18)

LCM = 20306662740/18

LCM = 1128147930

Thus, we can understand that the LCM of 371,678,117,690 is 1128147930.
