Given numbers are 938,420,572,884

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

The LCM of 938,420,572,884 is 68408340.

Find LCM of 938,420,572,884 with Prime Factorization

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

2 x 2 x 7 x 13 x 67 x 15 x 11 x 17 = 68408340

Therefore, the lowest common multiple of 938,420,572,884 is 68408340.

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.

938 x 420 x 572 x 884 = 199205086080

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.

938 : 1, 2, 7, 14, 67, 134, 469, 938

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 938,420,572,884, is 2.

Now, the common factors can be found like this.

938:2x 7x 67

420:2x 2x 3x 5x 7

572:2x 2x 11x 13

884:2x 2x 13x 17

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 7x 13 = 1456

Therefore, the value for common factors is 1456.

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 = 199205086080/(2x1456)

LCM = 199205086080/2912

LCM = 68408340

Thus, we can understand that the LCM of 938,420,572,884 is 68408340.
