Calculate the LCM of 661,724,737,407

Given numbers are 661,724,737,407

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

The LCM of 661,724,737,407 is 13049961716.

Find LCM of 661,724,737,407 with Prime Factorization


11 661, 724, 737, 407
661, 724, 67, 37

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

11 x 661 x 724 x 67 x 37 = 13049961716

Therefore, the lowest common multiple of 661,724,737,407 is 13049961716.

LCM Formula to Find Lowest Common Multiple of 661,724,737,407

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.

661 x 724 x 737 x 407 = 143549578876

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.

661 : 1, 661

724 : 1, 2, 4, 181, 362, 724

737 : 1, 11, 67, 737

407 : 1, 11, 37, 407

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,724,737,407, is 1.

Now, the common factors can be found like this.

661:661

724:2x 2x 181

737:11x 67

407:11x 37

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

11 = 11

Therefore, the value for common factors is 11.

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 = 143549578876/(1x11)

LCM = 143549578876/11

LCM = 13049961716

Thus, we can understand that the LCM of 661,724,737,407 is 13049961716.
