Calculate the LCM of 978,851,896,778

Given numbers are 978,851,896,778

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

The LCM of 978,851,896,778 is 145042751616.

Find LCM of 978,851,896,778 with Prime Factorization


2 978, 851, 896, 778
489, 851, 448, 389

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

2 x 489 x 851 x 448 x 389 = 145042751616

Therefore, the lowest common multiple of 978,851,896,778 is 145042751616.

LCM Formula to Find Lowest Common Multiple of 978,851,896,778

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 851 x 896 x 778 = 580171006464

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

851 : 1, 23, 37, 851

896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,851,896,778, is 1.

Now, the common factors can be found like this.

978:2x 3x 163

851:23x 37

896:2x 2x 2x 2x 2x 2x 2x 7

778:2x 389

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 = 580171006464/(1x4)

LCM = 580171006464/4

LCM = 145042751616

Thus, we can understand that the LCM of 978,851,896,778 is 145042751616.
