Calculate the LCM of 414,711,122,639

Given numbers are 414,711,122,639

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

The LCM of 414,711,122,639 is 141649686.

Find LCM of 414,711,122,639 with Prime Factorization


2 414, 711, 122, 639
3 207, 711, 61, 639
3 69, 237, 61, 213
23, 79, 61, 71

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

2 x 3 x 3 x 23 x 79 x 61 x 71 = 141649686

Therefore, the lowest common multiple of 414,711,122,639 is 141649686.

LCM Formula to Find Lowest Common Multiple of 414,711,122,639

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.

414 x 711 x 122 x 639 = 22947249132

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.

414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414

711 : 1, 3, 9, 79, 237, 711

122 : 1, 2, 61, 122

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 414,711,122,639, is 1.

Now, the common factors can be found like this.

414:2x 3x 3x 23

711:3x 3x 79

122:2x 61

639:3x 3x 71

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 3x 3 = 162

Therefore, the value for common factors is 162.

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 = 22947249132/(1x162)

LCM = 22947249132/162

LCM = 141649686

Thus, we can understand that the LCM of 414,711,122,639 is 141649686.
