Given numbers are 124,900,620,624,638

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

The LCM of 124,900,620,624,638 is 462805200.

Find LCM of 124,900,620,624,638 with Prime Factorization

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

2 x 2 x 3 x 5 x 31 x 1 x 15 x 1 x 52 x 319 = 462805200

Therefore, the lowest common multiple of 124,900,620,624,638 is 462805200.

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.

124 x 900 x 620 x 624 x 638 = 27546165504000

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.

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

900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900

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

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

638 : 1, 2, 11, 22, 29, 58, 319, 638

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 124,900,620,624,638, is 2.

Now, the common factors can be found like this.

124:2x 2x 31

900:2x 2x 3x 3x 5x 5

620:2x 2x 5x 31

624:2x 2x 2x 2x 3x 13

638:2x 11x 29

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 5x 31 = 29760

Therefore, the value for common factors is 29760.

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 = 27546165504000/(2x29760)

LCM = 27546165504000/59520

LCM = 462805200

Thus, we can understand that the LCM of 124,900,620,624,638 is 462805200.
