Given numbers are 138,146,789,620

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

The LCM of 138,146,789,620 is 821333220.

Find LCM of 138,146,789,620 with Prime Factorization

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

2 x 3 x 23 x 73 x 263 x 310 = 821333220

Therefore, the lowest common multiple of 138,146,789,620 is 821333220.

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.

138 x 146 x 789 x 620 = 9855998640

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.

138 : 1, 2, 3, 6, 23, 46, 69, 138

146 : 1, 2, 73, 146

789 : 1, 3, 263, 789

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,146,789,620, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

146:2x 73

789:3x 263

620:2x 2x 5x 31

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

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 9855998640/(1x12)

LCM = 9855998640/12

LCM = 821333220

Thus, we can understand that the LCM of 138,146,789,620 is 821333220.
