Given numbers are 781,436,506,117

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

The LCM of 781,436,506,117 is 916328556.

Find LCM of 781,436,506,117 with Prime Factorization

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

2 x 11 x 71 x 218 x 23 x 117 = 916328556

Therefore, the lowest common multiple of 781,436,506,117 is 916328556.

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.

781 x 436 x 506 x 117 = 20159228232

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.

781 : 1, 11, 71, 781

436 : 1, 2, 4, 109, 218, 436

506 : 1, 2, 11, 22, 23, 46, 253, 506

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,436,506,117, is 1.

Now, the common factors can be found like this.

781:11x 71

436:2x 2x 109

506:2x 11x 23

117:3x 3x 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 = 20159228232/(1x22)

LCM = 20159228232/22

LCM = 916328556

Thus, we can understand that the LCM of 781,436,506,117 is 916328556.
