Calculate the LCM of 669,965,545,187,445

Given numbers are 669,965,545,187,445

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

The LCM of 669,965,545,187,445 is 1171147355895.

Find LCM of 669,965,545,187,445 with Prime Factorization


5 669, 965, 545, 187, 445
669, 193, 109, 187, 89

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

5 x 669 x 193 x 109 x 187 x 89 = 1171147355895

Therefore, the lowest common multiple of 669,965,545,187,445 is 1171147355895.

LCM Formula to Find Lowest Common Multiple of 669,965,545,187,445

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.

669 x 965 x 545 x 187 x 445 = 29278683897375

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.

669 : 1, 3, 223, 669

965 : 1, 5, 193, 965

545 : 1, 5, 109, 545

187 : 1, 11, 17, 187

445 : 1, 5, 89, 445

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,965,545,187,445, is 1.

Now, the common factors can be found like this.

669:3x 223

965:5x 193

545:5x 109

187:11x 17

445:5x 89

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 29278683897375/(1x25)

LCM = 29278683897375/25

LCM = 1171147355895

Thus, we can understand that the LCM of 669,965,545,187,445 is 1171147355895.
