Given numbers are 920,989,137,491

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

The LCM of 920,989,137,491 is 2661082520.

Find LCM of 920,989,137,491 with Prime Factorization

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

23 x 40 x 43 x 137 x 491 = 2661082520

Therefore, the lowest common multiple of 920,989,137,491 is 2661082520.

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.

920 x 989 x 137 x 491 = 61204897960

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.

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

989 : 1, 23, 43, 989

137 : 1, 137

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,989,137,491, is 1.

Now, the common factors can be found like this.

920:2x 2x 2x 5x 23

989:23x 43

137:137

491:491

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

23 = 23

Therefore, the value for common factors is 23.

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 = 61204897960/(1x23)

LCM = 61204897960/23

LCM = 2661082520

Thus, we can understand that the LCM of 920,989,137,491 is 2661082520.
