The LCM of 180,126,242,989 is 150782940.

Find LCM of 180,126,242,989 with Prime Factorization


2 180, 126, 242, 989
3 90, 63, 121, 989
3 30, 21, 121, 989
10, 7, 121, 989

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

2 x 3 x 3 x 10 x 7 x 121 x 989 = 150782940

Therefore, the lowest common multiple of 180,126,242,989 is 150782940.

LCM Formula to Find Lowest Common Multiple of 180,126,242,989

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.

180 x 126 x 242 x 989 = 5428185840

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.

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

242 : 1, 2, 11, 22, 121, 242

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 180,126,242,989, is 1.

Now, the common factors can be found like this.

180:2x 2x 3x 3x 5

126:2x 3x 3x 7

242:2x 11x 11

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.

2x 2x 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 5428185840/(1x36)

LCM = 5428185840/36

LCM = 150782940

Thus, we can understand that the LCM of 180,126,242,989 is 150782940.
