Given numbers are 155,242,638,677

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

The LCM of 155,242,638,677 is 736433830.

Find LCM of 155,242,638,677 with Prime Factorization

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

2 x 11 x 155 x 11 x 29 x 677 = 736433830

Therefore, the lowest common multiple of 155,242,638,677 is 736433830.

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.

155 x 242 x 638 x 677 = 16201544260

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.

155 : 1, 5, 31, 155

242 : 1, 2, 11, 22, 121, 242

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

677 : 1, 677

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,242,638,677, is 1.

Now, the common factors can be found like this.

155:5x 31

242:2x 11x 11

638:2x 11x 29

677:677

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 16201544260/(1x22)

LCM = 16201544260/22

LCM = 736433830

Thus, we can understand that the LCM of 155,242,638,677 is 736433830.

Here are some samples of LCM of two or more Numbers calculations.
