Find LCM of 412,639,702,647,972 with Prime Factorization
| 2 | 412, 639, 702, 647, 972 |
| 2 | 206, 639, 351, 647, 486 |
| 3 | 103, 639, 351, 647, 243 |
| 3 | 103, 213, 117, 647, 81 |
| 3 | 103, 71, 39, 647, 27 |
| 103, 71, 13, 647, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 103 x 71 x 13 x 647 x 9 = 59787372996
Therefore, the lowest common multiple of 412,639,702,647,972 is 59787372996.
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.
412 x 639 x 702 x 647 x 972 = 116226653104224
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.
412 : 1, 2, 4, 103, 206, 412
639 : 1, 3, 9, 71, 213, 639
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
647 : 1, 647
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 412,639,702,647,972, is 1.
Now, the common factors can be found like this.
412:2x 2x 103
639:3x 3x 71
702:2x 3x 3x 3x 13
647:647
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 3x 3x 3x 3 = 1944
Therefore, the value for common factors is 1944.
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 = 116226653104224/(1x1944)
LCM = 116226653104224/1944
LCM = 59787372996
Thus, we can understand that the LCM of 412,639,702,647,972 is 59787372996.
