The LCM of 715,979,978,722 is 22466845830.

Find LCM of 715,979,978,722 with Prime Factorization


2 715, 979, 978, 722
11 715, 979, 489, 361
65, 89, 489, 361

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

2 x 11 x 65 x 89 x 489 x 361 = 22466845830

Therefore, the lowest common multiple of 715,979,978,722 is 22466845830.

LCM Formula to Find Lowest Common Multiple of 715,979,978,722

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.

715 x 979 x 978 x 722 = 494270608260

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.

715 : 1, 5, 11, 13, 55, 65, 143, 715

979 : 1, 11, 89, 979

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

722 : 1, 2, 19, 38, 361, 722

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,979,978,722, is 1.

Now, the common factors can be found like this.

715:5x 11x 13

979:11x 89

978:2x 3x 163

722:2x 19x 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 11 = 22

Therefore, the value for common factors is 22.

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 = 494270608260/(1x22)

LCM = 494270608260/22

LCM = 22466845830

Thus, we can understand that the LCM of 715,979,978,722 is 22466845830.
