Given numbers are 418,964,161,420,160

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

The LCM of 418,964,161,420,160 is 3892516320.

Find LCM of 418,964,161,420,160 with Prime Factorization

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

2 x 2 x 5 x 7 x 209 x 241 x 23 x 3 x 8 = 3892516320

Therefore, the lowest common multiple of 418,964,161,420,160 is 3892516320.

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.

418 x 964 x 161 x 420 x 160 = 4359618278400

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.

418 : 1, 2, 11, 19, 22, 38, 209, 418

964 : 1, 2, 4, 241, 482, 964

161 : 1, 7, 23, 161

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,964,161,420,160, is 1.

Now, the common factors can be found like this.

418:2x 11x 19

964:2x 2x 241

161:7x 23

420:2x 2x 3x 5x 7

160:2x 2x 2x 2x 2x 5

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 5x 7 = 1120

Therefore, the value for common factors is 1120.

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 = 4359618278400/(1x1120)

LCM = 4359618278400/1120

LCM = 3892516320

Thus, we can understand that the LCM of 418,964,161,420,160 is 3892516320.
