Calculate the LCM of 128,283,526,947,138

Given numbers are 128,283,526,947,138

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

The LCM of 128,283,526,947,138 is 622517010816.

Find LCM of 128,283,526,947,138 with Prime Factorization


2 128, 283, 526, 947, 138
64, 283, 263, 947, 69

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

2 x 64 x 283 x 263 x 947 x 69 = 622517010816

Therefore, the lowest common multiple of 128,283,526,947,138 is 622517010816.

LCM Formula to Find Lowest Common Multiple of 128,283,526,947,138

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.

128 x 283 x 526 x 947 x 138 = 2490068043264

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.

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

283 : 1, 283

526 : 1, 2, 263, 526

947 : 1, 947

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 128,283,526,947,138, is 1.

Now, the common factors can be found like this.

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

283:283

526:2x 263

947:947

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 2 = 4

Therefore, the value for common factors is 4.

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 = 2490068043264/(1x4)

LCM = 2490068043264/4

LCM = 622517010816

Thus, we can understand that the LCM of 128,283,526,947,138 is 622517010816.
