Given numbers are 357,370,161,862

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

The LCM of 357,370,161,862 is 1309408170.

Find LCM of 357,370,161,862 with Prime Factorization

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

2 x 7 x 51 x 185 x 23 x 431 = 1309408170

Therefore, the lowest common multiple of 357,370,161,862 is 1309408170.

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.

357 x 370 x 161 x 862 = 18331714380

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.

357 : 1, 3, 7, 17, 21, 51, 119, 357

370 : 1, 2, 5, 10, 37, 74, 185, 370

161 : 1, 7, 23, 161

862 : 1, 2, 431, 862

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 357,370,161,862, is 1.

Now, the common factors can be found like this.

357:3x 7x 17

370:2x 5x 37

161:7x 23

862:2x 431

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 = 18331714380/(1x14)

LCM = 18331714380/14

LCM = 1309408170

Thus, we can understand that the LCM of 357,370,161,862 is 1309408170.
