Find LCM of 628,353,992,943,138 with Prime Factorization


2 628, 353, 992, 943, 138
2 314, 353, 496, 943, 69
23 157, 353, 248, 943, 69
157, 353, 248, 41, 3

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

2 x 2 x 23 x 157 x 353 x 248 x 41 x 3 = 155531720928

Therefore, the lowest common multiple of 628,353,992,943,138 is 155531720928.

LCM Formula to Find Lowest Common Multiple of 628,353,992,943,138

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.

628 x 353 x 992 x 943 x 138 = 28617836650752

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.

628 : 1, 2, 4, 157, 314, 628

353 : 1, 353

992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992

943 : 1, 23, 41, 943

138 : 1, 2, 3, 6, 23, 46, 69, 138

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,353,992,943,138, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

353:353

992:2x 2x 2x 2x 2x 31

943:23x 41

138:2x 3x 23

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 23 = 184

Therefore, the value for common factors is 184.

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 = 28617836650752/(1x184)

LCM = 28617836650752/184

LCM = 155531720928

Thus, we can understand that the LCM of 628,353,992,943,138 is 155531720928.
