Given numbers are 452,989,161,842

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

The LCM of 452,989,161,842 is 1317391516.

Find LCM of 452,989,161,842 with Prime Factorization

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

2 x 23 x 226 x 43 x 7 x 421 = 1317391516

Therefore, the lowest common multiple of 452,989,161,842 is 1317391516.

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.

452 x 989 x 161 x 842 = 60600009736

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.

452 : 1, 2, 4, 113, 226, 452

989 : 1, 23, 43, 989

161 : 1, 7, 23, 161

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 452,989,161,842, is 1.

Now, the common factors can be found like this.

452:2x 2x 113

989:23x 43

161:7x 23

842:2x 421

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 = 60600009736/(1x46)

LCM = 60600009736/46

LCM = 1317391516

Thus, we can understand that the LCM of 452,989,161,842 is 1317391516.
