Calculate the LCM of 722,117,147,689

Given numbers are 722,117,147,689

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

The LCM of 722,117,147,689 is 219378978.

Find LCM of 722,117,147,689 with Prime Factorization


3 722, 117, 147, 689
13 722, 39, 49, 689
722, 3, 49, 53

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

3 x 13 x 722 x 3 x 49 x 53 = 219378978

Therefore, the lowest common multiple of 722,117,147,689 is 219378978.

LCM Formula to Find Lowest Common Multiple of 722,117,147,689

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.

722 x 117 x 147 x 689 = 8555780142

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.

722 : 1, 2, 19, 38, 361, 722

117 : 1, 3, 9, 13, 39, 117

147 : 1, 3, 7, 21, 49, 147

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,117,147,689, is 1.

Now, the common factors can be found like this.

722:2x 19x 19

117:3x 3x 13

147:3x 7x 7

689:13x 53

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

3x 13 = 39

Therefore, the value for common factors is 39.

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 = 8555780142/(1x39)

LCM = 8555780142/39

LCM = 219378978

Thus, we can understand that the LCM of 722,117,147,689 is 219378978.
