Calculate the LCM of 189,716,742,397,521

Given numbers are 189,716,742,397,521

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

The LCM of 189,716,742,397,521 is 1483470539964.

Find LCM of 189,716,742,397,521 with Prime Factorization


2 189, 716, 742, 397, 521
7 189, 358, 371, 397, 521
27, 358, 53, 397, 521

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

2 x 7 x 27 x 358 x 53 x 397 x 521 = 1483470539964

Therefore, the lowest common multiple of 189,716,742,397,521 is 1483470539964.

LCM Formula to Find Lowest Common Multiple of 189,716,742,397,521

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.

189 x 716 x 742 x 397 x 521 = 20768587559496

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.

189 : 1, 3, 7, 9, 21, 27, 63, 189

716 : 1, 2, 4, 179, 358, 716

742 : 1, 2, 7, 14, 53, 106, 371, 742

397 : 1, 397

521 : 1, 521

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,716,742,397,521, is 1.

Now, the common factors can be found like this.

189:3x 3x 3x 7

716:2x 2x 179

742:2x 7x 53

397:397

521:521

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 20768587559496/(1x14)

LCM = 20768587559496/14

LCM = 1483470539964

Thus, we can understand that the LCM of 189,716,742,397,521 is 1483470539964.
