Given numbers are 78,46,637

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

The LCM of 78,46,637 is 87906.

Find LCM of 78,46,637 with Prime Factorization

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

2 x 13 x 3 x 23 x 49 = 87906

Therefore, the lowest common multiple of 78,46,637 is 87906.

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.

78 x 46 x 637 = 2285556

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.

78 : 1, 2, 3, 6, 13, 26, 39, 78

46 : 1, 2, 23, 46

637 : 1, 7, 13, 49, 91, 637

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 78,46,637, is 1.

Now, the common factors can be found like this.

78:2x 3x 13

46:2x 23

637:7x 7x 13

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 2285556/(1x26)

LCM = 2285556/26

LCM = 87906

Thus, we can understand that the LCM of 78,46,637 is 87906.

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

• LCM of 63, 80, 122
• LCM of 11, 92, 842
