Calculate the LCM of 345,130,703,646

Given numbers are 345,130,703,646

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

The LCM of 345,130,703,646 is 107200470.

Find LCM of 345,130,703,646 with Prime Factorization


2 345, 130, 703, 646
5 345, 65, 703, 323
19 69, 13, 703, 323
69, 13, 37, 17

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

2 x 5 x 19 x 69 x 13 x 37 x 17 = 107200470

Therefore, the lowest common multiple of 345,130,703,646 is 107200470.

LCM Formula to Find Lowest Common Multiple of 345,130,703,646

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.

345 x 130 x 703 x 646 = 20368089300

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.

345 : 1, 3, 5, 15, 23, 69, 115, 345

130 : 1, 2, 5, 10, 13, 26, 65, 130

703 : 1, 19, 37, 703

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,130,703,646, is 1.

Now, the common factors can be found like this.

345:3x 5x 23

130:2x 5x 13

703:19x 37

646:2x 17x 19

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

2x 5x 19 = 190

Therefore, the value for common factors is 190.

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 = 20368089300/(1x190)

LCM = 20368089300/190

LCM = 107200470

Thus, we can understand that the LCM of 345,130,703,646 is 107200470.
