The LCM of 616,759,154,972 is 3442824.
Find LCM of 616,759,154,972 with Prime Factorization
| 2 | 616, 759, 154, 972 |
| 2 | 308, 759, 77, 486 |
| 3 | 154, 759, 77, 243 |
| 7 | 154, 253, 77, 81 |
| 11 | 22, 253, 11, 81 |
| 2, 23, 1, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 2 x 23 x 1 x 81 = 3442824
Therefore, the lowest common multiple of 616,759,154,972 is 3442824.
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.
616 x 759 x 154 x 972 = 69985726272
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.
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
759 : 1, 3, 11, 23, 33, 69, 253, 759
154 : 1, 2, 7, 11, 14, 22, 77, 154
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 616,759,154,972, is 1.
Now, the common factors can be found like this.
616:2x 2x 2x 7x 11
759:3x 11x 23
154:2x 7x 11
972:2x 2x 3x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 7x 11x 11 = 20328
Therefore, the value for common factors is 20328.
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 = 69985726272/(1x20328)
LCM = 69985726272/20328
LCM = 3442824
Thus, we can understand that the LCM of 616,759,154,972 is 3442824.
