Calculate the LCM of 845,274,838,680

Given numbers are 845,274,838,680

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

The LCM of 845,274,838,680 is 6596752760.

Find LCM of 845,274,838,680 with Prime Factorization


2 845, 274, 838, 680
5 845, 137, 419, 340
169, 137, 419, 68

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

2 x 5 x 169 x 137 x 419 x 68 = 6596752760

Therefore, the lowest common multiple of 845,274,838,680 is 6596752760.

LCM Formula to Find Lowest Common Multiple of 845,274,838,680

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.

845 x 274 x 838 x 680 = 131935055200

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.

845 : 1, 5, 13, 65, 169, 845

274 : 1, 2, 137, 274

838 : 1, 2, 419, 838

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,274,838,680, is 1.

Now, the common factors can be found like this.

845:5x 13x 13

274:2x 137

838:2x 419

680:2x 2x 2x 5x 17

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 5 = 20

Therefore, the value for common factors is 20.

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 = 131935055200/(1x20)

LCM = 131935055200/20

LCM = 6596752760

Thus, we can understand that the LCM of 845,274,838,680 is 6596752760.
