Given numbers are 121,320,639,106,703

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

The LCM of 121,320,639,106,703 is 921865158720.

Find LCM of 121,320,639,106,703 with Prime Factorization

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

2 x 121 x 160 x 639 x 53 x 703 = 921865158720

Therefore, the lowest common multiple of 121,320,639,106,703 is 921865158720.

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.

121 x 320 x 639 x 106 x 703 = 1843730317440

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.

121 : 1, 11, 121

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

639 : 1, 3, 9, 71, 213, 639

106 : 1, 2, 53, 106

703 : 1, 19, 37, 703

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,320,639,106,703, is 1.

Now, the common factors can be found like this.

121:11x 11

320:2x 2x 2x 2x 2x 2x 5

639:3x 3x 71

106:2x 53

703:19x 37

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 = 1843730317440/(1x2)

LCM = 1843730317440/2

LCM = 921865158720

Thus, we can understand that the LCM of 121,320,639,106,703 is 921865158720.
