Given numbers are 620,868,163,792

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

The LCM of 620,868,163,792 is 140069160.

Find LCM of 620,868,163,792 with Prime Factorization

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

2 x 2 x 31 x 5 x 7 x 163 x 198 = 140069160

Therefore, the lowest common multiple of 620,868,163,792 is 140069160.

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.

620 x 868 x 163 x 792 = 69474303360

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.

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

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

163 : 1, 163

792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,868,163,792, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

868:2x 2x 7x 31

163:163

792:2x 2x 2x 3x 3x 11

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 31 = 496

Therefore, the value for common factors is 496.

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 = 69474303360/(1x496)

LCM = 69474303360/496

LCM = 140069160

Thus, we can understand that the LCM of 620,868,163,792 is 140069160.
