Calculate the LCM of 420,625,473,575

Given numbers are 420,625,473,575

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

The LCM of 420,625,473,575 is 571147500.

Find LCM of 420,625,473,575 with Prime Factorization


5 420, 625, 473, 575
5 84, 125, 473, 115
84, 25, 473, 23

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

5 x 5 x 84 x 25 x 473 x 23 = 571147500

Therefore, the lowest common multiple of 420,625,473,575 is 571147500.

LCM Formula to Find Lowest Common Multiple of 420,625,473,575

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.

420 x 625 x 473 x 575 = 71393437500

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.

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

625 : 1, 5, 25, 125, 625

473 : 1, 11, 43, 473

575 : 1, 5, 23, 25, 115, 575

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,625,473,575, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

625:5x 5x 5x 5

473:11x 43

575:5x 5x 23

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

5x 5x 5 = 125

Therefore, the value for common factors is 125.

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 = 71393437500/(1x125)

LCM = 71393437500/125

LCM = 571147500

Thus, we can understand that the LCM of 420,625,473,575 is 571147500.
