Calculate the LCM of 974,900,384,685

Given numbers are 974,900,384,685

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

The LCM of 974,900,384,685 is 1921507200.

Find LCM of 974,900,384,685 with Prime Factorization


2 974, 900, 384, 685
2 487, 450, 192, 685
3 487, 225, 96, 685
5 487, 75, 32, 685
487, 15, 32, 137

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

2 x 2 x 3 x 5 x 487 x 15 x 32 x 137 = 1921507200

Therefore, the lowest common multiple of 974,900,384,685 is 1921507200.

LCM Formula to Find Lowest Common Multiple of 974,900,384,685

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.

974 x 900 x 384 x 685 = 230580864000

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.

974 : 1, 2, 487, 974

900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900

384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384

685 : 1, 5, 137, 685

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,900,384,685, is 1.

Now, the common factors can be found like this.

974:2x 487

900:2x 2x 3x 3x 5x 5

384:2x 2x 2x 2x 2x 2x 2x 3

685:5x 137

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 3x 5 = 120

Therefore, the value for common factors is 120.

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 = 230580864000/(1x120)

LCM = 230580864000/120

LCM = 1921507200

Thus, we can understand that the LCM of 974,900,384,685 is 1921507200.
