Calculate the LCM of 770,478,750,392

Given numbers are 770,478,750,392

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

The LCM of 770,478,750,392 is 386463000.

Find LCM of 770,478,750,392 with Prime Factorization


2 770, 478, 750, 392
5 385, 239, 375, 196
7 77, 239, 75, 196
11, 239, 75, 28

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

2 x 5 x 7 x 11 x 239 x 75 x 28 = 386463000

Therefore, the lowest common multiple of 770,478,750,392 is 386463000.

LCM Formula to Find Lowest Common Multiple of 770,478,750,392

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 478 x 750 x 392 = 108209640000

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

478 : 1, 2, 239, 478

750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,478,750,392, is 2.

Now, the common factors can be found like this.

770:2x 5x 7x 11

478:2x 239

750:2x 3x 5x 5x 5

392:2x 2x 2x 7x 7

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 5x 7 = 140

Therefore, the value for common factors is 140.

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 = 108209640000/(2x140)

LCM = 108209640000/280

LCM = 386463000

Thus, we can understand that the LCM of 770,478,750,392 is 386463000.
