Given numbers are 121,556,262,974

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

The LCM of 121,556,262,974 is 4292006972.

Find LCM of 121,556,262,974 with Prime Factorization

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

2 x 121 x 278 x 131 x 487 = 4292006972

Therefore, the lowest common multiple of 121,556,262,974 is 4292006972.

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.

121 x 556 x 262 x 974 = 17168027888

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.

121 : 1, 11, 121

556 : 1, 2, 4, 139, 278, 556

262 : 1, 2, 131, 262

974 : 1, 2, 487, 974

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,556,262,974, is 1.

Now, the common factors can be found like this.

121:11x 11

556:2x 2x 139

262:2x 131

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 = 17168027888/(1x4)

LCM = 17168027888/4

LCM = 4292006972

Thus, we can understand that the LCM of 121,556,262,974 is 4292006972.
