Given numbers are 161,974,154,711

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

The LCM of 161,974,154,711 is 1226442294.

Find LCM of 161,974,154,711 with Prime Factorization

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

2 x 7 x 23 x 487 x 11 x 711 = 1226442294

Therefore, the lowest common multiple of 161,974,154,711 is 1226442294.

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.

161 x 974 x 154 x 711 = 17170192116

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.

161 : 1, 7, 23, 161

974 : 1, 2, 487, 974

154 : 1, 2, 7, 11, 14, 22, 77, 154

711 : 1, 3, 9, 79, 237, 711

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,974,154,711, is 1.

Now, the common factors can be found like this.

161:7x 23

974:2x 487

154:2x 7x 11

711:3x 3x 79

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 17170192116/(1x14)

LCM = 17170192116/14

LCM = 1226442294

Thus, we can understand that the LCM of 161,974,154,711 is 1226442294.
