Given numbers are 651,381,857,690

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

The LCM of 651,381,857,690 is 16296463470.

Find LCM of 651,381,857,690 with Prime Factorization

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

3 x 217 x 127 x 857 x 230 = 16296463470

Therefore, the lowest common multiple of 651,381,857,690 is 16296463470.

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.

651 x 381 x 857 x 690 = 146668171230

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.

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

381 : 1, 3, 127, 381

857 : 1, 857

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 651,381,857,690, is 1.

Now, the common factors can be found like this.

651:3x 7x 31

381:3x 127

857:857

690:2x 3x 5x 23

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 146668171230/(1x9)

LCM = 146668171230/9

LCM = 16296463470

Thus, we can understand that the LCM of 651,381,857,690 is 16296463470.
