Given numbers are 177,708,538,420

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

The LCM of 177,708,538,420 is 6665820.

Find LCM of 177,708,538,420 with Prime Factorization

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

2 x 2 x 3 x 59 x 1 x 1 x 269 x 35 = 6665820

Therefore, the lowest common multiple of 177,708,538,420 is 6665820.

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.

177 x 708 x 538 x 420 = 28316403360

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.

177 : 1, 3, 59, 177

708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708

538 : 1, 2, 269, 538

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 177,708,538,420, is 1.

Now, the common factors can be found like this.

177:3x 59

708:2x 2x 3x 59

538:2x 269

420:2x 2x 3x 5x 7

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 59 = 4248

Therefore, the value for common factors is 4248.

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 = 28316403360/(1x4248)

LCM = 28316403360/4248

LCM = 6665820

Thus, we can understand that the LCM of 177,708,538,420 is 6665820.
