Given numbers are 409,409,169,820

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

The LCM of 409,409,169,820 is 56679220.

Find LCM of 409,409,169,820 with Prime Factorization

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

409 x 1 x 1 x 169 x 820 = 56679220

Therefore, the lowest common multiple of 409,409,169,820 is 56679220.

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.

409 x 409 x 169 x 820 = 23181800980

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.

409 : 1, 409

409 : 1, 409

169 : 1, 13, 169

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,409,169,820, is 1.

Now, the common factors can be found like this.

409:409

409:409

169:13x 13

820:2x 2x 5x 41

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

409 = 409

Therefore, the value for common factors is 409.

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 = 23181800980/(1x409)

LCM = 23181800980/409

LCM = 56679220

Thus, we can understand that the LCM of 409,409,169,820 is 56679220.
