Given numbers are 728,274,997,202,780

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

The LCM of 728,274,997,202,780 is 150646739880.

Find LCM of 728,274,997,202,780 with Prime Factorization

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

2 x 2 x 13 x 14 x 137 x 997 x 101 x 15 = 150646739880

Therefore, the lowest common multiple of 728,274,997,202,780 is 150646739880.

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.

728 x 274 x 997 x 202 x 780 = 31334521895040

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.

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

274 : 1, 2, 137, 274

997 : 1, 997

202 : 1, 2, 101, 202

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,274,997,202,780, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

274:2x 137

997:997

202:2x 101

780:2x 2x 3x 5x 13

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 2x 13 = 208

Therefore, the value for common factors is 208.

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 = 31334521895040/(1x208)

LCM = 31334521895040/208

LCM = 150646739880

Thus, we can understand that the LCM of 728,274,997,202,780 is 150646739880.
