Calculate the LCM of 722,969,474,320

Given numbers are 722,969,474,320

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

The LCM of 722,969,474,320 is 465430080.

Find LCM of 722,969,474,320 with Prime Factorization


2 722, 969, 474, 320
3 361, 969, 237, 160
19 361, 323, 79, 160
19, 17, 79, 160

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

2 x 3 x 19 x 19 x 17 x 79 x 160 = 465430080

Therefore, the lowest common multiple of 722,969,474,320 is 465430080.

LCM Formula to Find Lowest Common Multiple of 722,969,474,320

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.

722 x 969 x 474 x 320 = 106118058240

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.

722 : 1, 2, 19, 38, 361, 722

969 : 1, 3, 17, 19, 51, 57, 323, 969

474 : 1, 2, 3, 6, 79, 158, 237, 474

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,969,474,320, is 1.

Now, the common factors can be found like this.

722:2x 19x 19

969:3x 17x 19

474:2x 3x 79

320:2x 2x 2x 2x 2x 2x 5

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

2x 2x 3x 19 = 228

Therefore, the value for common factors is 228.

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 = 106118058240/(1x228)

LCM = 106118058240/228

LCM = 465430080

Thus, we can understand that the LCM of 722,969,474,320 is 465430080.
