Given numbers are 126,638,438,643,116

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

The LCM of 126,638,438,643,116 is 3773332332.

Find LCM of 126,638,438,643,116 with Prime Factorization

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

2 x 3 x 29 x 21 x 11 x 73 x 643 x 2 = 3773332332

Therefore, the lowest common multiple of 126,638,438,643,116 is 3773332332.

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.

126 x 638 x 438 x 643 x 116 = 2626239303072

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.

126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

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

438 : 1, 2, 3, 6, 73, 146, 219, 438

643 : 1, 643

116 : 1, 2, 4, 29, 58, 116

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,638,438,643,116, is 1.

Now, the common factors can be found like this.

126:2x 3x 3x 7

638:2x 11x 29

438:2x 3x 73

643:643

116:2x 2x 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 3x 29 = 696

Therefore, the value for common factors is 696.

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 = 2626239303072/(1x696)

LCM = 2626239303072/696

LCM = 3773332332

Thus, we can understand that the LCM of 126,638,438,643,116 is 3773332332.
