Calculate the LCM of 120,398,689,467,812

Given numbers are 120,398,689,467,812

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

The LCM of 120,398,689,467,812 is 1559791189320.

Find LCM of 120,398,689,467,812 with Prime Factorization


2 120, 398, 689, 467, 812
2 60, 199, 689, 467, 406
30, 199, 689, 467, 203

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

2 x 2 x 30 x 199 x 689 x 467 x 203 = 1559791189320

Therefore, the lowest common multiple of 120,398,689,467,812 is 1559791189320.

LCM Formula to Find Lowest Common Multiple of 120,398,689,467,812

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.

120 x 398 x 689 x 467 x 812 = 12478329514560

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.

120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

398 : 1, 2, 199, 398

689 : 1, 13, 53, 689

467 : 1, 467

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 120,398,689,467,812, is 1.

Now, the common factors can be found like this.

120:2x 2x 2x 3x 5

398:2x 199

689:13x 53

467:467

812:2x 2x 7x 29

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 2 = 8

Therefore, the value for common factors is 8.

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 = 12478329514560/(1x8)

LCM = 12478329514560/8

LCM = 1559791189320

Thus, we can understand that the LCM of 120,398,689,467,812 is 1559791189320.
