Given numbers are 151,840,981,651,721

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

The LCM of 151,840,981,651,721 is 132435039240.

Find LCM of 151,840,981,651,721 with Prime Factorization

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

3 x 7 x 151 x 40 x 327 x 31 x 103 = 132435039240

Therefore, the lowest common multiple of 151,840,981,651,721 is 132435039240.

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.

151 x 840 x 981 x 651 x 721 = 58403852304840

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.

151 : 1, 151

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

981 : 1, 3, 9, 109, 327, 981

651 : 1, 3, 7, 21, 31, 93, 217, 651

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 151,840,981,651,721, is 1.

Now, the common factors can be found like this.

151:151

840:2x 2x 2x 3x 5x 7

981:3x 3x 109

651:3x 7x 31

721:7x 103

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

3x 3x 7x 7 = 441

Therefore, the value for common factors is 441.

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 = 58403852304840/(1x441)

LCM = 58403852304840/441

LCM = 132435039240

Thus, we can understand that the LCM of 151,840,981,651,721 is 132435039240.
