Given numbers are 988,316,198,64

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

The LCM of 988,316,198,64 is 123634368.

Find LCM of 988,316,198,64 with Prime Factorization

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

2 x 2 x 247 x 79 x 99 x 16 = 123634368

Therefore, the lowest common multiple of 988,316,198,64 is 123634368.

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.

988 x 316 x 198 x 64 = 3956299776

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.

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

316 : 1, 2, 4, 79, 158, 316

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

64 : 1, 2, 4, 8, 16, 32, 64

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,316,198,64, is 2.

Now, the common factors can be found like this.

988:2x 2x 13x 19

316:2x 2x 79

198:2x 3x 3x 11

64:2x 2x 2x 2x 2x 2

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 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 3956299776/(2x16)

LCM = 3956299776/32

LCM = 123634368

Thus, we can understand that the LCM of 988,316,198,64 is 123634368.
