Calculate the LCM of 980,525,691,169

Given numbers are 980,525,691,169

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

The LCM of 980,525,691,169 is 1716651300.

Find LCM of 980,525,691,169 with Prime Factorization


5 980, 525, 691, 169
7 196, 105, 691, 169
28, 15, 691, 169

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

5 x 7 x 28 x 15 x 691 x 169 = 1716651300

Therefore, the lowest common multiple of 980,525,691,169 is 1716651300.

LCM Formula to Find Lowest Common Multiple of 980,525,691,169

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.

980 x 525 x 691 x 169 = 60082795500

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.

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

525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525

691 : 1, 691

169 : 1, 13, 169

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,525,691,169, is 1.

Now, the common factors can be found like this.

980:2x 2x 5x 7x 7

525:3x 5x 5x 7

691:691

169:13x 13

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

5x 7 = 35

Therefore, the value for common factors is 35.

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 = 60082795500/(1x35)

LCM = 60082795500/35

LCM = 1716651300

Thus, we can understand that the LCM of 980,525,691,169 is 1716651300.
