Calculate the LCM of 772,398,128,148

Given numbers are 772,398,128,148

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

The LCM of 772,398,128,148 is 181895552.

Find LCM of 772,398,128,148 with Prime Factorization


2 772, 398, 128, 148
2 386, 199, 64, 74
193, 199, 32, 37

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

2 x 2 x 193 x 199 x 32 x 37 = 181895552

Therefore, the lowest common multiple of 772,398,128,148 is 181895552.

LCM Formula to Find Lowest Common Multiple of 772,398,128,148

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.

772 x 398 x 128 x 148 = 5820657664

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.

772 : 1, 2, 4, 193, 386, 772

398 : 1, 2, 199, 398

128 : 1, 2, 4, 8, 16, 32, 64, 128

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,398,128,148, is 2.

Now, the common factors can be found like this.

772:2x 2x 193

398:2x 199

128:2x 2x 2x 2x 2x 2x 2

148:2x 2x 37

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 2 = 16

Therefore, the value for common factors is 16.

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 = 5820657664/(2x16)

LCM = 5820657664/32

LCM = 181895552

Thus, we can understand that the LCM of 772,398,128,148 is 181895552.
