Find LCM of 252,451,820,728 with Prime Factorization


2 252, 451, 820, 728
2 126, 451, 410, 364
7 63, 451, 205, 182
41 9, 451, 205, 26
9, 11, 5, 26

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

2 x 2 x 7 x 41 x 9 x 11 x 5 x 26 = 14774760

Therefore, the lowest common multiple of 252,451,820,728 is 14774760.

LCM Formula to Find Lowest Common Multiple of 252,451,820,728

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.

252 x 451 x 820 x 728 = 67845697920

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.

252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252

451 : 1, 11, 41, 451

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 252,451,820,728, is 1.

Now, the common factors can be found like this.

252:2x 2x 3x 3x 7

451:11x 41

820:2x 2x 5x 41

728:2x 2x 2x 7x 13

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

2x 2x 2x 2x 7x 41 = 4592

Therefore, the value for common factors is 4592.

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 = 67845697920/(1x4592)

LCM = 67845697920/4592

LCM = 14774760

Thus, we can understand that the LCM of 252,451,820,728 is 14774760.
