Given numbers are 851,407,218,981

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

The LCM of 851,407,218,981 is 18366282.

Find LCM of 851,407,218,981 with Prime Factorization

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

37 x 109 x 23 x 11 x 2 x 9 = 18366282

Therefore, the lowest common multiple of 851,407,218,981 is 18366282.

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.

851 x 407 x 218 x 981 = 74071215306

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.

851 : 1, 23, 37, 851

407 : 1, 11, 37, 407

218 : 1, 2, 109, 218

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,407,218,981, is 1.

Now, the common factors can be found like this.

851:23x 37

407:11x 37

218:2x 109

981:3x 3x 109

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

37x 109 = 4033

Therefore, the value for common factors is 4033.

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 = 74071215306/(1x4033)

LCM = 74071215306/4033

LCM = 18366282

Thus, we can understand that the LCM of 851,407,218,981 is 18366282.
