The LCM of 983,980,171,441 is 164731140.

Find LCM of 983,980,171,441 with Prime Factorization


3 983, 980, 171, 441
3 983, 980, 57, 147
7 983, 980, 19, 49
7 983, 140, 19, 7
983, 20, 19, 1

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

3 x 3 x 7 x 7 x 983 x 20 x 19 x 1 = 164731140

Therefore, the lowest common multiple of 983,980,171,441 is 164731140.

LCM Formula to Find Lowest Common Multiple of 983,980,171,441

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.

983 x 980 x 171 x 441 = 72646432740

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.

983 : 1, 983

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

171 : 1, 3, 9, 19, 57, 171

441 : 1, 3, 7, 9, 21, 49, 63, 147, 441

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 983,980,171,441, is 1.

Now, the common factors can be found like this.

983:983

980:2x 2x 5x 7x 7

171:3x 3x 19

441:3x 3x 7x 7

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

3x 3x 7x 7 = 441

Therefore, the value for common factors is 441.

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 = 72646432740/(1x441)

LCM = 72646432740/441

LCM = 164731140

Thus, we can understand that the LCM of 983,980,171,441 is 164731140.
