Given numbers are 420,620,272,876,722

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

The LCM of 420,620,272,876,722 is 23331892080.

Find LCM of 420,620,272,876,722 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 68 x 73 x 361 = 23331892080

Therefore, the lowest common multiple of 420,620,272,876,722 is 23331892080.

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 620 x 272 x 876 x 722 = 44797232793600

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

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876

722 : 1, 2, 19, 38, 361, 722

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,620,272,876,722, is 2.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

620:2x 2x 5x 31

272:2x 2x 2x 2x 17

876:2x 2x 3x 73

722:2x 19x 19

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 2x 2x 2x 2x 3x 5 = 960

Therefore, the value for common factors is 960.

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 = 44797232793600/(2x960)

LCM = 44797232793600/1920

LCM = 23331892080

Thus, we can understand that the LCM of 420,620,272,876,722 is 23331892080.
