The LCM of 611,828,987,442 is 60203052.

Find LCM of 611,828,987,442 with Prime Factorization


2 611, 828, 987, 442
3 611, 414, 987, 221
13 611, 138, 329, 221
47 47, 138, 329, 17
1, 138, 7, 17

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

2 x 3 x 13 x 47 x 1 x 138 x 7 x 17 = 60203052

Therefore, the lowest common multiple of 611,828,987,442 is 60203052.

LCM Formula to Find Lowest Common Multiple of 611,828,987,442

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.

611 x 828 x 987 x 442 = 220704388632

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.

611 : 1, 13, 47, 611

828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828

987 : 1, 3, 7, 21, 47, 141, 329, 987

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 611,828,987,442, is 1.

Now, the common factors can be found like this.

611:13x 47

828:2x 2x 3x 3x 23

987:3x 7x 47

442:2x 13x 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 13x 47 = 3666

Therefore, the value for common factors is 3666.

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 = 220704388632/(1x3666)

LCM = 220704388632/3666

LCM = 60203052

Thus, we can understand that the LCM of 611,828,987,442 is 60203052.
