Given numbers are 667,614,402,781

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

The LCM of 667,614,402,781 is 64289684778.

Find LCM of 667,614,402,781 with Prime Factorization

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

2 x 667 x 307 x 201 x 781 = 64289684778

Therefore, the lowest common multiple of 667,614,402,781 is 64289684778.

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.

667 x 614 x 402 x 781 = 128579369556

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.

667 : 1, 23, 29, 667

614 : 1, 2, 307, 614

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

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,614,402,781, is 1.

Now, the common factors can be found like this.

667:23x 29

614:2x 307

402:2x 3x 67

781:11x 71

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

2 = 2

Therefore, the value for common factors is 2.

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 = 128579369556/(1x2)

LCM = 128579369556/2

LCM = 64289684778

Thus, we can understand that the LCM of 667,614,402,781 is 64289684778.
