Given numbers are 781,555,434,221,302

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

The LCM of 781,555,434,221,302 is 6277734833370.

Find LCM of 781,555,434,221,302 with Prime Factorization

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

2 x 781 x 555 x 217 x 221 x 151 = 6277734833370

Therefore, the lowest common multiple of 781,555,434,221,302 is 6277734833370.

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 555 x 434 x 221 x 302 = 12555469666740

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

555 : 1, 3, 5, 15, 37, 111, 185, 555

434 : 1, 2, 7, 14, 31, 62, 217, 434

221 : 1, 13, 17, 221

302 : 1, 2, 151, 302

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,555,434,221,302, is 1.

Now, the common factors can be found like this.

781:11x 71

555:3x 5x 37

434:2x 7x 31

221:13x 17

302:2x 151

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 = 12555469666740/(1x2)

LCM = 12555469666740/2

LCM = 6277734833370

Thus, we can understand that the LCM of 781,555,434,221,302 is 6277734833370.
