Given numbers are 778,273,479,980

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

The LCM of 778,273,479,980 is 7121570820.

Find LCM of 778,273,479,980 with Prime Factorization

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

2 x 7 x 389 x 39 x 479 x 70 = 7121570820

Therefore, the lowest common multiple of 778,273,479,980 is 7121570820.

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 273 x 479 x 980 = 99701991480

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

273 : 1, 3, 7, 13, 21, 39, 91, 273

479 : 1, 479

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,273,479,980, is 1.

Now, the common factors can be found like this.

778:2x 389

273:3x 7x 13

479:479

980:2x 2x 5x 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 7 = 14

Therefore, the value for common factors is 14.

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 = 99701991480/(1x14)

LCM = 99701991480/14

LCM = 7121570820

Thus, we can understand that the LCM of 778,273,479,980 is 7121570820.
