Calculate the LCM of 145,989,989,784

Given numbers are 145,989,989,784

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

The LCM of 145,989,989,784 is 112429520.

Find LCM of 145,989,989,784 with Prime Factorization


23 145, 989, 989, 784
43 145, 43, 43, 784
145, 1, 1, 784

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

23 x 43 x 145 x 1 x 1 x 784 = 112429520

Therefore, the lowest common multiple of 145,989,989,784 is 112429520.

LCM Formula to Find Lowest Common Multiple of 145,989,989,784

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.

145 x 989 x 989 x 784 = 111192795280

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.

145 : 1, 5, 29, 145

989 : 1, 23, 43, 989

989 : 1, 23, 43, 989

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 145,989,989,784, is 1.

Now, the common factors can be found like this.

145:5x 29

989:23x 43

989:23x 43

784:2x 2x 2x 2x 7x 7

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

23x 43 = 989

Therefore, the value for common factors is 989.

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 = 111192795280/(1x989)

LCM = 111192795280/989

LCM = 112429520

Thus, we can understand that the LCM of 145,989,989,784 is 112429520.
