Calculate the LCM of 609,393,129,989

Given numbers are 609,393,129,989

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

The LCM of 609,393,129,989 is 78901431.

Find LCM of 609,393,129,989 with Prime Factorization


3 609, 393, 129, 989
43 203, 131, 43, 989
203, 131, 1, 23

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

3 x 43 x 203 x 131 x 1 x 23 = 78901431

Therefore, the lowest common multiple of 609,393,129,989 is 78901431.

LCM Formula to Find Lowest Common Multiple of 609,393,129,989

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.

609 x 393 x 129 x 989 = 30534853797

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.

609 : 1, 3, 7, 21, 29, 87, 203, 609

393 : 1, 3, 131, 393

129 : 1, 3, 43, 129

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,393,129,989, is 1.

Now, the common factors can be found like this.

609:3x 7x 29

393:3x 131

129:3x 43

989:23x 43

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

3x 3x 43 = 387

Therefore, the value for common factors is 387.

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 = 30534853797/(1x387)

LCM = 30534853797/387

LCM = 78901431

Thus, we can understand that the LCM of 609,393,129,989 is 78901431.
