Given numbers are 978,995,730,77

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

The LCM of 978,995,730,77 is 5469851310.

Find LCM of 978,995,730,77 with Prime Factorization

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

2 x 5 x 489 x 199 x 73 x 77 = 5469851310

Therefore, the lowest common multiple of 978,995,730,77 is 5469851310.

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.

978 x 995 x 730 x 77 = 54698513100

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.

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

995 : 1, 5, 199, 995

730 : 1, 2, 5, 10, 73, 146, 365, 730

77 : 1, 7, 11, 77

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,995,730,77, is 1.

Now, the common factors can be found like this.

978:2x 3x 163

995:5x 199

730:2x 5x 73

77:7x 11

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 54698513100/(1x10)

LCM = 54698513100/10

LCM = 5469851310

Thus, we can understand that the LCM of 978,995,730,77 is 5469851310.
