Given numbers are 638,880,124,984,246

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

The LCM of 638,880,124,984,246 is 97307760.

Find LCM of 638,880,124,984,246 with Prime Factorization

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

2 x 2 x 2 x 3 x 11 x 41 x 29 x 10 x 31 x 1 x 1 = 97307760

Therefore, the lowest common multiple of 638,880,124,984,246 is 97307760.

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.

638 x 880 x 124 x 984 x 246 = 16852147107840

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.

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

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

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

984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984

246 : 1, 2, 3, 6, 41, 82, 123, 246

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,880,124,984,246, is 2.

Now, the common factors can be found like this.

638:2x 11x 29

880:2x 2x 2x 2x 5x 11

124:2x 2x 31

984:2x 2x 2x 3x 41

246:2x 3x 41

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 11x 41 = 86592

Therefore, the value for common factors is 86592.

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 = 16852147107840/(2x86592)

LCM = 16852147107840/173184

LCM = 97307760

Thus, we can understand that the LCM of 638,880,124,984,246 is 97307760.
