Calculate the LCM of 985,780,265,785

Given numbers are 985,780,265,785

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

The LCM of 985,780,265,785 is 1278604860.

Find LCM of 985,780,265,785 with Prime Factorization


5 985, 780, 265, 785
197, 156, 53, 157

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

5 x 197 x 156 x 53 x 157 = 1278604860

Therefore, the lowest common multiple of 985,780,265,785 is 1278604860.

LCM Formula to Find Lowest Common Multiple of 985,780,265,785

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.

985 x 780 x 265 x 785 = 159825607500

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.

985 : 1, 5, 197, 985

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

265 : 1, 5, 53, 265

785 : 1, 5, 157, 785

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,780,265,785, is 5.

Now, the common factors can be found like this.

985:5x 197

780:2x 2x 3x 5x 13

265:5x 53

785:5x 157

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 159825607500/(5x25)

LCM = 159825607500/125

LCM = 1278604860

Thus, we can understand that the LCM of 985,780,265,785 is 1278604860.
