Calculate the LCM of 72,98,969

Given numbers are 72,98,969

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

The LCM of 72,98,969 is 1139544.

Find LCM of 72,98,969 with Prime Factorization


2 72, 98, 969
3 36, 49, 969
12, 49, 323

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

2 x 3 x 12 x 49 x 323 = 1139544

Therefore, the lowest common multiple of 72,98,969 is 1139544.

LCM Formula to Find Lowest Common Multiple of 72,98,969

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.

72 x 98 x 969 = 6837264

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.

72 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

98 : 1, 2, 7, 14, 49, 98

969 : 1, 3, 17, 19, 51, 57, 323, 969

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 72,98,969, is 1.

Now, the common factors can be found like this.

72:2x 2x 2x 3x 3

98:2x 7x 7

969:3x 17x 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 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 = 6837264/(1x6)

LCM = 6837264/6

LCM = 1139544

Thus, we can understand that the LCM of 72,98,969 is 1139544.
