Given numbers are 672,973,713,435,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 672,973,713,435,391 is 164168763360.
Find LCM of 672,973,713,435,391 with Prime Factorization
| 3 | 672, 973, 713, 435, 391 |
| 7 | 224, 973, 713, 145, 391 |
| 23 | 32, 139, 713, 145, 391 |
| 32, 139, 31, 145, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 23 x 32 x 139 x 31 x 145 x 17 = 164168763360
Therefore, the lowest common multiple of 672,973,713,435,391 is 164168763360.
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.
672 x 973 x 713 x 435 x 391 = 79293512702880
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.
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
973 : 1, 7, 139, 973
713 : 1, 23, 31, 713
435 : 1, 3, 5, 15, 29, 87, 145, 435
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,973,713,435,391, is 1.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
973:7x 139
713:23x 31
435:3x 5x 29
391:17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 23 = 483
Therefore, the value for common factors is 483.
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 = 79293512702880/(1x483)
LCM = 79293512702880/483
LCM = 164168763360
Thus, we can understand that the LCM of 672,973,713,435,391 is 164168763360.
