Given numbers are 781,402,247,670

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

The LCM of 781,402,247,670 is 387743070.

Find LCM of 781,402,247,670 with Prime Factorization

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

2 x 67 x 781 x 3 x 247 x 5 = 387743070

Therefore, the lowest common multiple of 781,402,247,670 is 387743070.

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.

781 x 402 x 247 x 670 = 51957571380

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.

781 : 1, 11, 71, 781

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

247 : 1, 13, 19, 247

670 : 1, 2, 5, 10, 67, 134, 335, 670

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,402,247,670, is 1.

Now, the common factors can be found like this.

781:11x 71

402:2x 3x 67

247:13x 19

670:2x 5x 67

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 67 = 134

Therefore, the value for common factors is 134.

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 = 51957571380/(1x134)

LCM = 51957571380/134

LCM = 387743070

Thus, we can understand that the LCM of 781,402,247,670 is 387743070.
