Given numbers are 651,460,771,321,420

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

The LCM of 651,460,771,321,420 is 8234850540.

Find LCM of 651,460,771,321,420 with Prime Factorization

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

2 x 2 x 3 x 5 x 7 x 31 x 23 x 257 x 107 x 1 = 8234850540

Therefore, the lowest common multiple of 651,460,771,321,420 is 8234850540.

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 460 x 771 x 321 x 420 = 31127735041200

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

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

771 : 1, 3, 257, 771

321 : 1, 3, 107, 321

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 651,460,771,321,420, is 1.

Now, the common factors can be found like this.

651:3x 7x 31

460:2x 2x 5x 23

771:3x 257

321:3x 107

420:2x 2x 3x 5x 7

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

2x 2x 3x 3x 3x 5x 7 = 3780

Therefore, the value for common factors is 3780.

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 = 31127735041200/(1x3780)

LCM = 31127735041200/3780

LCM = 8234850540

Thus, we can understand that the LCM of 651,460,771,321,420 is 8234850540.
