Calculate the LCM of 934,987,840,790

Given numbers are 934,987,840,790

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

The LCM of 934,987,840,790 is 1456535640.

Find LCM of 934,987,840,790 with Prime Factorization


2 934, 987, 840, 790
3 467, 987, 420, 395
5 467, 329, 140, 395
7 467, 329, 28, 79
467, 47, 4, 79

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

2 x 3 x 5 x 7 x 467 x 47 x 4 x 79 = 1456535640

Therefore, the lowest common multiple of 934,987,840,790 is 1456535640.

LCM Formula to Find Lowest Common Multiple of 934,987,840,790

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.

934 x 987 x 840 x 790 = 611744968800

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.

934 : 1, 2, 467, 934

987 : 1, 3, 7, 21, 47, 141, 329, 987

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

790 : 1, 2, 5, 10, 79, 158, 395, 790

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 934,987,840,790, is 1.

Now, the common factors can be found like this.

934:2x 467

987:3x 7x 47

840:2x 2x 2x 3x 5x 7

790:2x 5x 79

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 3x 5x 7 = 420

Therefore, the value for common factors is 420.

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 = 611744968800/(1x420)

LCM = 611744968800/420

LCM = 1456535640

Thus, we can understand that the LCM of 934,987,840,790 is 1456535640.
