Given numbers are 402,392,772,790,161

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

The LCM of 402,392,772,790,161 is 138154286760.

Find LCM of 402,392,772,790,161 with Prime Factorization

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

2 x 2 x 7 x 201 x 14 x 193 x 395 x 23 = 138154286760

Therefore, the lowest common multiple of 402,392,772,790,161 is 138154286760.

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 392 x 772 x 790 x 161 = 15473280117120

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

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

772 : 1, 2, 4, 193, 386, 772

790 : 1, 2, 5, 10, 79, 158, 395, 790

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,392,772,790,161, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

392:2x 2x 2x 7x 7

772:2x 2x 193

790:2x 5x 79

161:7x 23

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 7 = 112

Therefore, the value for common factors is 112.

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 = 15473280117120/(1x112)

LCM = 15473280117120/112

LCM = 138154286760

Thus, we can understand that the LCM of 402,392,772,790,161 is 138154286760.
