Calculate the LCM of 409,781,425,710

Given numbers are 409,781,425,710

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

The LCM of 409,781,425,710 is 271514650.

Find LCM of 409,781,425,710 with Prime Factorization


5 409, 781, 425, 710
71 409, 781, 85, 142
409, 11, 85, 2

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

5 x 71 x 409 x 11 x 85 x 2 = 271514650

Therefore, the lowest common multiple of 409,781,425,710 is 271514650.

LCM Formula to Find Lowest Common Multiple of 409,781,425,710

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.

409 x 781 x 425 x 710 = 96387700750

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.

409 : 1, 409

781 : 1, 11, 71, 781

425 : 1, 5, 17, 25, 85, 425

710 : 1, 2, 5, 10, 71, 142, 355, 710

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,781,425,710, is 1.

Now, the common factors can be found like this.

409:409

781:11x 71

425:5x 5x 17

710:2x 5x 71

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

5x 71 = 355

Therefore, the value for common factors is 355.

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 = 96387700750/(1x355)

LCM = 96387700750/355

LCM = 271514650

Thus, we can understand that the LCM of 409,781,425,710 is 271514650.
