Calculate the LCM of 985,638,831,169,978

Given numbers are 985,638,831,169,978

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

The LCM of 985,638,831,169,978 is 14385741165510.

Find LCM of 985,638,831,169,978 with Prime Factorization


2 985, 638, 831, 169, 978
3 985, 319, 831, 169, 489
985, 319, 277, 169, 163

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

2 x 3 x 985 x 319 x 277 x 169 x 163 = 14385741165510

Therefore, the lowest common multiple of 985,638,831,169,978 is 14385741165510.

LCM Formula to Find Lowest Common Multiple of 985,638,831,169,978

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.

985 x 638 x 831 x 169 x 978 = 86314446993060

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.

985 : 1, 5, 197, 985

638 : 1, 2, 11, 22, 29, 58, 319, 638

831 : 1, 3, 277, 831

169 : 1, 13, 169

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 985,638,831,169,978, is 1.

Now, the common factors can be found like this.

985:5x 197

638:2x 11x 29

831:3x 277

169:13x 13

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 3 = 6

Therefore, the value for common factors is 6.

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 = 86314446993060/(1x6)

LCM = 86314446993060/6

LCM = 14385741165510

Thus, we can understand that the LCM of 985,638,831,169,978 is 14385741165510.
