Given numbers are 770,394,341,621

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

The LCM of 770,394,341,621 is 2920184190.

Find LCM of 770,394,341,621 with Prime Factorization

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

2 x 11 x 35 x 197 x 31 x 621 = 2920184190

Therefore, the lowest common multiple of 770,394,341,621 is 2920184190.

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.

770 x 394 x 341 x 621 = 64244052180

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.

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

394 : 1, 2, 197, 394

341 : 1, 11, 31, 341

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,394,341,621, is 1.

Now, the common factors can be found like this.

770:2x 5x 7x 11

394:2x 197

341:11x 31

621:3x 3x 3x 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 11 = 22

Therefore, the value for common factors is 22.

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 = 64244052180/(1x22)

LCM = 64244052180/22

LCM = 2920184190

Thus, we can understand that the LCM of 770,394,341,621 is 2920184190.

Here are some samples of LCM of two or more Numbers calculations.
