Given numbers are 122,156,791,860,988

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

The LCM of 122,156,791,860,988 is 30748432260.

Find LCM of 122,156,791,860,988 with Prime Factorization

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

2 x 2 x 13 x 61 x 3 x 791 x 215 x 19 = 30748432260

Therefore, the lowest common multiple of 122,156,791,860,988 is 30748432260.

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 156 x 791 x 860 x 988 = 12791347820160

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

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

791 : 1, 7, 113, 791

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,156,791,860,988, is 1.

Now, the common factors can be found like this.

122:2x 61

156:2x 2x 3x 13

791:7x 113

860:2x 2x 5x 43

988:2x 2x 13x 19

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 2x 2x 2x 13 = 416

Therefore, the value for common factors is 416.

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 = 12791347820160/(1x416)

LCM = 12791347820160/416

LCM = 30748432260

Thus, we can understand that the LCM of 122,156,791,860,988 is 30748432260.
