Calculate the LCM of 978,961,902,851

Given numbers are 978,961,902,851

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

The LCM of 978,961,902,851 is 360718440258.

Find LCM of 978,961,902,851 with Prime Factorization


2 978, 961, 902, 851
489, 961, 451, 851

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

2 x 489 x 961 x 451 x 851 = 360718440258

Therefore, the lowest common multiple of 978,961,902,851 is 360718440258.

LCM Formula to Find Lowest Common Multiple of 978,961,902,851

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 961 x 902 x 851 = 721436880516

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

961 : 1, 31, 961

902 : 1, 2, 11, 22, 41, 82, 451, 902

851 : 1, 23, 37, 851

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,961,902,851, is 1.

Now, the common factors can be found like this.

978:2x 3x 163

961:31x 31

902:2x 11x 41

851:23x 37

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

2 = 2

Therefore, the value for common factors is 2.

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 = 721436880516/(1x2)

LCM = 721436880516/2

LCM = 360718440258

Thus, we can understand that the LCM of 978,961,902,851 is 360718440258.
