Given numbers are 158,161,437,970

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

The LCM of 158,161,437,970 is 234411170.

Find LCM of 158,161,437,970 with Prime Factorization

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

2 x 23 x 79 x 7 x 19 x 485 = 234411170

Therefore, the lowest common multiple of 158,161,437,970 is 234411170.

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.

158 x 161 x 437 x 970 = 10782913820

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.

158 : 1, 2, 79, 158

161 : 1, 7, 23, 161

437 : 1, 19, 23, 437

970 : 1, 2, 5, 10, 97, 194, 485, 970

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 158,161,437,970, is 1.

Now, the common factors can be found like this.

158:2x 79

161:7x 23

437:19x 23

970:2x 5x 97

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

2x 23 = 46

Therefore, the value for common factors is 46.

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 = 10782913820/(1x46)

LCM = 10782913820/46

LCM = 234411170

Thus, we can understand that the LCM of 158,161,437,970 is 234411170.
