Given numbers are 420,344,771,532,124

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

The LCM of 420,344,771,532,124 is 5467592760.

Find LCM of 420,344,771,532,124 with Prime Factorization

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

2 x 2 x 3 x 7 x 5 x 86 x 257 x 19 x 31 = 5467592760

Therefore, the lowest common multiple of 420,344,771,532,124 is 5467592760.

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 344 x 771 x 532 x 124 = 7348444669440

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

344 : 1, 2, 4, 8, 43, 86, 172, 344

771 : 1, 3, 257, 771

532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532

124 : 1, 2, 4, 31, 62, 124

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,344,771,532,124, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

344:2x 2x 2x 43

771:3x 257

532:2x 2x 7x 19

124:2x 2x 31

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 7 = 1344

Therefore, the value for common factors is 1344.

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 = 7348444669440/(1x1344)

LCM = 7348444669440/1344

LCM = 5467592760

Thus, we can understand that the LCM of 420,344,771,532,124 is 5467592760.
