Given numbers are 742,641,636

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

The LCM of 742,641,636 is 2853732.

Find LCM of 742,641,636 with Prime Factorization

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

2 x 53 x 7 x 641 x 6 = 2853732

Therefore, the lowest common multiple of 742,641,636 is 2853732.

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.

742 x 641 x 636 = 302495592

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.

742 : 1, 2, 7, 14, 53, 106, 371, 742

641 : 1, 641

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,641,636, is 1.

Now, the common factors can be found like this.

742:2x 7x 53

641:641

636:2x 2x 3x 53

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

2x 53 = 106

Therefore, the value for common factors is 106.

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 = 302495592/(1x106)

LCM = 302495592/106

LCM = 2853732

Thus, we can understand that the LCM of 742,641,636 is 2853732.

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