Calculate the LCM of 665,285,517,977

Given numbers are 665,285,517,977

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

The LCM of 665,285,517,977 is 1007692455.

Find LCM of 665,285,517,977 with Prime Factorization


5 665, 285, 517, 977
19 133, 57, 517, 977
7, 3, 517, 977

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

5 x 19 x 7 x 3 x 517 x 977 = 1007692455

Therefore, the lowest common multiple of 665,285,517,977 is 1007692455.

LCM Formula to Find Lowest Common Multiple of 665,285,517,977

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.

665 x 285 x 517 x 977 = 95730783225

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.

665 : 1, 5, 7, 19, 35, 95, 133, 665

285 : 1, 3, 5, 15, 19, 57, 95, 285

517 : 1, 11, 47, 517

977 : 1, 977

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,285,517,977, is 1.

Now, the common factors can be found like this.

665:5x 7x 19

285:3x 5x 19

517:11x 47

977:977

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

5x 19 = 95

Therefore, the value for common factors is 95.

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 = 95730783225/(1x95)

LCM = 95730783225/95

LCM = 1007692455

Thus, we can understand that the LCM of 665,285,517,977 is 1007692455.
