Calculate the LCM of 345,102,695,510

Given numbers are 345,102,695,510

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

The LCM of 345,102,695,510 is 1630470.

Find LCM of 345,102,695,510 with Prime Factorization


2 345, 102, 695, 510
3 345, 51, 695, 255
5 115, 17, 695, 85
17 23, 17, 139, 17
23, 1, 139, 1

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

2 x 3 x 5 x 17 x 23 x 1 x 139 x 1 = 1630470

Therefore, the lowest common multiple of 345,102,695,510 is 1630470.

LCM Formula to Find Lowest Common Multiple of 345,102,695,510

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 102 x 695 x 510 = 12473095500

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

102 : 1, 2, 3, 6, 17, 34, 51, 102

695 : 1, 5, 139, 695

510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,102,695,510, is 1.

Now, the common factors can be found like this.

345:3x 5x 23

102:2x 3x 17

695:5x 139

510:2x 3x 5x 17

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

2x 3x 3x 5x 5x 17 = 7650

Therefore, the value for common factors is 7650.

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 = 12473095500/(1x7650)

LCM = 12473095500/7650

LCM = 1630470

Thus, we can understand that the LCM of 345,102,695,510 is 1630470.
