Calculate the LCM of 398,921,644,685,473

Given numbers are 398,921,644,685,473

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

The LCM of 398,921,644,685,473 is 38242853182380.

Find LCM of 398,921,644,685,473 with Prime Factorization


2 398, 921, 644, 685, 473
199, 921, 322, 685, 473

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

2 x 199 x 921 x 322 x 685 x 473 = 38242853182380

Therefore, the lowest common multiple of 398,921,644,685,473 is 38242853182380.

LCM Formula to Find Lowest Common Multiple of 398,921,644,685,473

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.

398 x 921 x 644 x 685 x 473 = 76485706364760

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.

398 : 1, 2, 199, 398

921 : 1, 3, 307, 921

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

685 : 1, 5, 137, 685

473 : 1, 11, 43, 473

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,921,644,685,473, is 1.

Now, the common factors can be found like this.

398:2x 199

921:3x 307

644:2x 2x 7x 23

685:5x 137

473:11x 43

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

2 = 2

Therefore, the value for common factors is 2.

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 = 76485706364760/(1x2)

LCM = 76485706364760/2

LCM = 38242853182380

Thus, we can understand that the LCM of 398,921,644,685,473 is 38242853182380.
