Given numbers are 251,728,274,129,974

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

The LCM of 251,728,274,129,974 is 1572694396728.

Find LCM of 251,728,274,129,974 with Prime Factorization

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

2 x 251 x 364 x 137 x 129 x 487 = 1572694396728

Therefore, the lowest common multiple of 251,728,274,129,974 is 1572694396728.

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.

251 x 728 x 274 x 129 x 974 = 6290777586912

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.

251 : 1, 251

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

274 : 1, 2, 137, 274

129 : 1, 3, 43, 129

974 : 1, 2, 487, 974

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,728,274,129,974, is 1.

Now, the common factors can be found like this.

251:251

728:2x 2x 2x 7x 13

274:2x 137

129:3x 43

974:2x 487

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 6290777586912/(1x4)

LCM = 6290777586912/4

LCM = 1572694396728

Thus, we can understand that the LCM of 251,728,274,129,974 is 1572694396728.
