Calculate the LCM of 680,838,646,602

Given numbers are 680,838,646,602

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

The LCM of 680,838,646,602 is 1629457480.

Find LCM of 680,838,646,602 with Prime Factorization


2 680, 838, 646, 602
17 340, 419, 323, 301
20, 419, 19, 301

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

2 x 17 x 20 x 419 x 19 x 301 = 1629457480

Therefore, the lowest common multiple of 680,838,646,602 is 1629457480.

LCM Formula to Find Lowest Common Multiple of 680,838,646,602

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.

680 x 838 x 646 x 602 = 221606217280

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.

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

838 : 1, 2, 419, 838

646 : 1, 2, 17, 19, 34, 38, 323, 646

602 : 1, 2, 7, 14, 43, 86, 301, 602

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,838,646,602, is 2.

Now, the common factors can be found like this.

680:2x 2x 2x 5x 17

838:2x 419

646:2x 17x 19

602:2x 7x 43

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 17 = 68

Therefore, the value for common factors is 68.

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 = 221606217280/(2x68)

LCM = 221606217280/136

LCM = 1629457480

Thus, we can understand that the LCM of 680,838,646,602 is 1629457480.
