Calculate the LCM of 122,397,370,470

Given numbers are 122,397,370,470

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

The LCM of 122,397,370,470 is 421133630.

Find LCM of 122,397,370,470 with Prime Factorization


2 122, 397, 370, 470
5 61, 397, 185, 235
61, 397, 37, 47

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

2 x 5 x 61 x 397 x 37 x 47 = 421133630

Therefore, the lowest common multiple of 122,397,370,470 is 421133630.

LCM Formula to Find Lowest Common Multiple of 122,397,370,470

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.

122 x 397 x 370 x 470 = 8422672600

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.

122 : 1, 2, 61, 122

397 : 1, 397

370 : 1, 2, 5, 10, 37, 74, 185, 370

470 : 1, 2, 5, 10, 47, 94, 235, 470

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,397,370,470, is 1.

Now, the common factors can be found like this.

122:2x 61

397:397

370:2x 5x 37

470:2x 5x 47

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 5 = 20

Therefore, the value for common factors is 20.

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 = 8422672600/(1x20)

LCM = 8422672600/20

LCM = 421133630

Thus, we can understand that the LCM of 122,397,370,470 is 421133630.
