Given numbers are 193,117,780,247,644

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

The LCM of 193,117,780,247,644 is 1381505580.

Find LCM of 193,117,780,247,644 with Prime Factorization

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

2 x 2 x 3 x 13 x 193 x 3 x 5 x 19 x 161 = 1381505580

Therefore, the lowest common multiple of 193,117,780,247,644 is 1381505580.

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.

193 x 117 x 780 x 247 x 644 = 2801693316240

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.

193 : 1, 193

117 : 1, 3, 9, 13, 39, 117

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

247 : 1, 13, 19, 247

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 193,117,780,247,644, is 1.

Now, the common factors can be found like this.

193:193

117:3x 3x 13

780:2x 2x 3x 5x 13

247:13x 19

644:2x 2x 7x 23

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 3x 13x 13 = 2028

Therefore, the value for common factors is 2028.

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 = 2801693316240/(1x2028)

LCM = 2801693316240/2028

LCM = 1381505580

Thus, we can understand that the LCM of 193,117,780,247,644 is 1381505580.
