Given numbers are 402,681,970,744

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

The LCM of 402,681,970,744 is 5488015560.

Find LCM of 402,681,970,744 with Prime Factorization

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

2 x 3 x 67 x 227 x 485 x 124 = 5488015560

Therefore, the lowest common multiple of 402,681,970,744 is 5488015560.

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.

402 x 681 x 970 x 744 = 197568560160

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.

402 : 1, 2, 3, 6, 67, 134, 201, 402

681 : 1, 3, 227, 681

970 : 1, 2, 5, 10, 97, 194, 485, 970

744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,681,970,744, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

681:3x 227

970:2x 5x 97

744:2x 2x 2x 3x 31

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 3 = 36

Therefore, the value for common factors is 36.

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 = 197568560160/(1x36)

LCM = 197568560160/36

LCM = 5488015560

Thus, we can understand that the LCM of 402,681,970,744 is 5488015560.
