Calculate the LCM of 545,651,378,388

Given numbers are 545,651,378,388

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

The LCM of 545,651,378,388 is 1238944140.

Find LCM of 545,651,378,388 with Prime Factorization


2 545, 651, 378, 388
3 545, 651, 189, 194
7 545, 217, 63, 194
545, 31, 9, 194

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

2 x 3 x 7 x 545 x 31 x 9 x 194 = 1238944140

Therefore, the lowest common multiple of 545,651,378,388 is 1238944140.

LCM Formula to Find Lowest Common Multiple of 545,651,378,388

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.

545 x 651 x 378 x 388 = 52035653880

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.

545 : 1, 5, 109, 545

651 : 1, 3, 7, 21, 31, 93, 217, 651

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

388 : 1, 2, 4, 97, 194, 388

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,651,378,388, is 1.

Now, the common factors can be found like this.

545:5x 109

651:3x 7x 31

378:2x 3x 3x 3x 7

388:2x 2x 97

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 7 = 42

Therefore, the value for common factors is 42.

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 = 52035653880/(1x42)

LCM = 52035653880/42

LCM = 1238944140

Thus, we can understand that the LCM of 545,651,378,388 is 1238944140.
