Given numbers are 770,198,397,988

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

The LCM of 770,198,397,988 is 1359097740.

Find LCM of 770,198,397,988 with Prime Factorization

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

2 x 11 x 35 x 9 x 397 x 494 = 1359097740

Therefore, the lowest common multiple of 770,198,397,988 is 1359097740.

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 198 x 397 x 988 = 59800300560

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

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

397 : 1, 397

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,198,397,988, is 1.

Now, the common factors can be found like this.

770:2x 5x 7x 11

198:2x 3x 3x 11

397:397

988:2x 2x 13x 19

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 11 = 44

Therefore, the value for common factors is 44.

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 = 59800300560/(1x44)

LCM = 59800300560/44

LCM = 1359097740

Thus, we can understand that the LCM of 770,198,397,988 is 1359097740.
