Find LCM of 361,648,148,399 with Prime Factorization


2 361, 648, 148, 399
2 361, 324, 74, 399
3 361, 162, 37, 399
19 361, 54, 37, 133
19, 54, 37, 7

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

2 x 2 x 3 x 19 x 19 x 54 x 37 x 7 = 60587352

Therefore, the lowest common multiple of 361,648,148,399 is 60587352.

LCM Formula to Find Lowest Common Multiple of 361,648,148,399

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.

361 x 648 x 148 x 399 = 13813916256

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.

361 : 1, 19, 361

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

148 : 1, 2, 4, 37, 74, 148

399 : 1, 3, 7, 19, 21, 57, 133, 399

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,648,148,399, is 1.

Now, the common factors can be found like this.

361:19x 19

648:2x 2x 2x 3x 3x 3x 3

148:2x 2x 37

399:3x 7x 19

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 3x 19 = 228

Therefore, the value for common factors is 228.

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 = 13813916256/(1x228)

LCM = 13813916256/228

LCM = 60587352

Thus, we can understand that the LCM of 361,648,148,399 is 60587352.
