Calculate the LCM of 492,720,711,974

Given numbers are 492,720,711,974

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

The LCM of 492,720,711,974 is 1135722960.

Find LCM of 492,720,711,974 with Prime Factorization


2 492, 720, 711, 974
2 246, 360, 711, 487
3 123, 180, 711, 487
3 41, 60, 237, 487
41, 20, 79, 487

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

2 x 2 x 3 x 3 x 41 x 20 x 79 x 487 = 1135722960

Therefore, the lowest common multiple of 492,720,711,974 is 1135722960.

LCM Formula to Find Lowest Common Multiple of 492,720,711,974

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.

492 x 720 x 711 x 974 = 245316159360

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.

492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

711 : 1, 3, 9, 79, 237, 711

974 : 1, 2, 487, 974

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 492,720,711,974, is 1.

Now, the common factors can be found like this.

492:2x 2x 3x 41

720:2x 2x 2x 2x 3x 3x 5

711:3x 3x 79

974:2x 487

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 3x 3 = 216

Therefore, the value for common factors is 216.

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 = 245316159360/(1x216)

LCM = 245316159360/216

LCM = 1135722960

Thus, we can understand that the LCM of 492,720,711,974 is 1135722960.
