Calculate the LCM of 189,434,235,655,770

Given numbers are 189,434,235,655,770

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

The LCM of 189,434,235,655,770 is 3968124930.

Find LCM of 189,434,235,655,770 with Prime Factorization


2 189, 434, 235, 655, 770
5 189, 217, 235, 655, 385
7 189, 217, 47, 131, 77
27, 31, 47, 131, 11

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

2 x 5 x 7 x 27 x 31 x 47 x 131 x 11 = 3968124930

Therefore, the lowest common multiple of 189,434,235,655,770 is 3968124930.

LCM Formula to Find Lowest Common Multiple of 189,434,235,655,770

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.

189 x 434 x 235 x 655 x 770 = 9721906078500

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.

189 : 1, 3, 7, 9, 21, 27, 63, 189

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

235 : 1, 5, 47, 235

655 : 1, 5, 131, 655

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,434,235,655,770, is 1.

Now, the common factors can be found like this.

189:3x 3x 3x 7

434:2x 7x 31

235:5x 47

655:5x 131

770:2x 5x 7x 11

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

2x 5x 5x 7x 7 = 2450

Therefore, the value for common factors is 2450.

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 = 9721906078500/(1x2450)

LCM = 9721906078500/2450

LCM = 3968124930

Thus, we can understand that the LCM of 189,434,235,655,770 is 3968124930.
