Given numbers are 139,420,553

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

The LCM of 139,420,553 is 4612020.

Find LCM of 139,420,553 with Prime Factorization

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

7 x 139 x 60 x 79 = 4612020

Therefore, the lowest common multiple of 139,420,553 is 4612020.

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.

139 x 420 x 553 = 32284140

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.

139 : 1, 139

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

553 : 1, 7, 79, 553

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 139,420,553, is 1.

Now, the common factors can be found like this.

139:139

420:2x 2x 3x 5x 7

553:7x 79

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

7 = 7

Therefore, the value for common factors is 7.

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 = 32284140/(1x7)

LCM = 32284140/7

LCM = 4612020

Thus, we can understand that the LCM of 139,420,553 is 4612020.

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