Given numbers are 178,706,689,978

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

The LCM of 178,706,689,978 is 21170094114.

Find LCM of 178,706,689,978 with Prime Factorization

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

2 x 89 x 353 x 689 x 489 = 21170094114

Therefore, the lowest common multiple of 178,706,689,978 is 21170094114.

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.

178 x 706 x 689 x 978 = 84680376456

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.

178 : 1, 2, 89, 178

706 : 1, 2, 353, 706

689 : 1, 13, 53, 689

978 : 1, 2, 3, 6, 163, 326, 489, 978

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 178,706,689,978, is 1.

Now, the common factors can be found like this.

178:2x 89

706:2x 353

689:13x 53

978:2x 3x 163

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 84680376456/(1x4)

LCM = 84680376456/4

LCM = 21170094114

Thus, we can understand that the LCM of 178,706,689,978 is 21170094114.
