The LCM of 571,663,103,420 is 5459022660.

Find LCM of 571,663,103,420 with Prime Factorization


3 571, 663, 103, 420
571, 221, 103, 140

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

3 x 571 x 221 x 103 x 140 = 5459022660

Therefore, the lowest common multiple of 571,663,103,420 is 5459022660.

LCM Formula to Find Lowest Common Multiple of 571,663,103,420

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.

571 x 663 x 103 x 420 = 16377067980

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.

571 : 1, 571

663 : 1, 3, 13, 17, 39, 51, 221, 663

103 : 1, 103

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 571,663,103,420, is 1.

Now, the common factors can be found like this.

571:571

663:3x 13x 17

103:103

420:2x 2x 3x 5x 7

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

3 = 3

Therefore, the value for common factors is 3.

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 = 16377067980/(1x3)

LCM = 16377067980/3

LCM = 5459022660

Thus, we can understand that the LCM of 571,663,103,420 is 5459022660.
