Find LCM of 899,455,124,780 with Prime Factorization


2 899, 455, 124, 780
2 899, 455, 62, 390
5 899, 455, 31, 195
13 899, 91, 31, 39
31 899, 7, 31, 3
29, 7, 1, 3

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

2 x 2 x 5 x 13 x 31 x 29 x 7 x 1 x 3 = 4908540

Therefore, the lowest common multiple of 899,455,124,780 is 4908540.

LCM Formula to Find Lowest Common Multiple of 899,455,124,780

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.

899 x 455 x 124 x 780 = 39562832400

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.

899 : 1, 29, 31, 899

455 : 1, 5, 7, 13, 35, 65, 91, 455

124 : 1, 2, 4, 31, 62, 124

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 899,455,124,780, is 1.

Now, the common factors can be found like this.

899:29x 31

455:5x 7x 13

124:2x 2x 31

780:2x 2x 3x 5x 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 5x 13x 31 = 8060

Therefore, the value for common factors is 8060.

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 = 39562832400/(1x8060)

LCM = 39562832400/8060

LCM = 4908540

Thus, we can understand that the LCM of 899,455,124,780 is 4908540.
