Calculate the LCM of 772,706,221,351

Given numbers are 772,706,221,351

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

The LCM of 772,706,221,351 is 1626102972.

Find LCM of 772,706,221,351 with Prime Factorization


2 772, 706, 221, 351
13 386, 353, 221, 351
386, 353, 17, 27

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

2 x 13 x 386 x 353 x 17 x 27 = 1626102972

Therefore, the lowest common multiple of 772,706,221,351 is 1626102972.

LCM Formula to Find Lowest Common Multiple of 772,706,221,351

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.

772 x 706 x 221 x 351 = 42278677272

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.

772 : 1, 2, 4, 193, 386, 772

706 : 1, 2, 353, 706

221 : 1, 13, 17, 221

351 : 1, 3, 9, 13, 27, 39, 117, 351

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,706,221,351, is 1.

Now, the common factors can be found like this.

772:2x 2x 193

706:2x 353

221:13x 17

351:3x 3x 3x 13

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 42278677272/(1x26)

LCM = 42278677272/26

LCM = 1626102972

Thus, we can understand that the LCM of 772,706,221,351 is 1626102972.
