Given numbers are 102,920,163,661

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

The LCM of 102,920,163,661 is 5055301560.

Find LCM of 102,920,163,661 with Prime Factorization

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

2 x 51 x 460 x 163 x 661 = 5055301560

Therefore, the lowest common multiple of 102,920,163,661 is 5055301560.

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.

102 x 920 x 163 x 661 = 10110603120

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.

102 : 1, 2, 3, 6, 17, 34, 51, 102

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

163 : 1, 163

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 102,920,163,661, is 1.

Now, the common factors can be found like this.

102:2x 3x 17

920:2x 2x 2x 5x 23

163:163

661:661

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

2 = 2

Therefore, the value for common factors is 2.

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 = 10110603120/(1x2)

LCM = 10110603120/2

LCM = 5055301560

Thus, we can understand that the LCM of 102,920,163,661 is 5055301560.
