Calculate the LCM of 742,421,863,790

Given numbers are 742,421,863,790

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

The LCM of 742,421,863,790 is 106486338070.

Find LCM of 742,421,863,790 with Prime Factorization


2 742, 421, 863, 790
371, 421, 863, 395

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

2 x 371 x 421 x 863 x 395 = 106486338070

Therefore, the lowest common multiple of 742,421,863,790 is 106486338070.

LCM Formula to Find Lowest Common Multiple of 742,421,863,790

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.

742 x 421 x 863 x 790 = 212972676140

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.

742 : 1, 2, 7, 14, 53, 106, 371, 742

421 : 1, 421

863 : 1, 863

790 : 1, 2, 5, 10, 79, 158, 395, 790

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,421,863,790, is 1.

Now, the common factors can be found like this.

742:2x 7x 53

421:421

863:863

790:2x 5x 79

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

2 = 2

Therefore, the value for common factors is 2.

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 = 212972676140/(1x2)

LCM = 212972676140/2

LCM = 106486338070

Thus, we can understand that the LCM of 742,421,863,790 is 106486338070.
