Calculate the LCM of 689,397,397,287

Given numbers are 689,397,397,287

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

The LCM of 689,397,397,287 is 78503971.

Find LCM of 689,397,397,287 with Prime Factorization

397	689, 397, 397, 287
	689, 1, 1, 287

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

397 x 689 x 1 x 1 x 287 = 78503971

Therefore, the lowest common multiple of 689,397,397,287 is 78503971.

LCM Formula to Find Lowest Common Multiple of 689,397,397,287

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.

689 x 397 x 397 x 287 = 31166076487

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.

689 : 1, 13, 53, 689

397 : 1, 397

287 : 1, 7, 41, 287

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,397,397,287, is 1.

Now, the common factors can be found like this.

689:13x 53

397:397

287:7x 41

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

397 = 397

Therefore, the value for common factors is 397.

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 = 31166076487/(1x397)

LCM = 31166076487/397

LCM = 78503971

Thus, we can understand that the LCM of 689,397,397,287 is 78503971.
