Given numbers are 778,771,341,392

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

The LCM of 778,771,341,392 is 40090772568.

Find LCM of 778,771,341,392 with Prime Factorization

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

2 x 389 x 771 x 341 x 196 = 40090772568

Therefore, the lowest common multiple of 778,771,341,392 is 40090772568.

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.

778 x 771 x 341 x 392 = 80181545136

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.

778 : 1, 2, 389, 778

771 : 1, 3, 257, 771

341 : 1, 11, 31, 341

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,771,341,392, is 1.

Now, the common factors can be found like this.

778:2x 389

771:3x 257

341:11x 31

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.

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 = 80181545136/(1x2)

LCM = 80181545136/2

LCM = 40090772568

Thus, we can understand that the LCM of 778,771,341,392 is 40090772568.
