Given numbers are 420,851,889,274

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

The LCM of 420,851,889,274 is 6218750580.

Find LCM of 420,851,889,274 with Prime Factorization

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

2 x 7 x 30 x 851 x 127 x 137 = 6218750580

Therefore, the lowest common multiple of 420,851,889,274 is 6218750580.

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.

420 x 851 x 889 x 274 = 87062508120

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.

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

851 : 1, 23, 37, 851

889 : 1, 7, 127, 889

274 : 1, 2, 137, 274

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,851,889,274, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

851:23x 37

889:7x 127

274:2x 137

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 87062508120/(1x14)

LCM = 87062508120/14

LCM = 6218750580

Thus, we can understand that the LCM of 420,851,889,274 is 6218750580.
