Given numbers are 402,101,169,169

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

The LCM of 402,101,169,169 is 6861738.

Find LCM of 402,101,169,169 with Prime Factorization

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

13 x 13 x 402 x 101 x 1 x 1 = 6861738

Therefore, the lowest common multiple of 402,101,169,169 is 6861738.

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.

402 x 101 x 169 x 169 = 1159633722

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.

402 : 1, 2, 3, 6, 67, 134, 201, 402

101 : 1, 101

169 : 1, 13, 169

169 : 1, 13, 169

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,101,169,169, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

101:101

169:13x 13

169:13x 13

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 1159633722/(1x169)

LCM = 1159633722/169

LCM = 6861738

Thus, we can understand that the LCM of 402,101,169,169 is 6861738.
