Given numbers are 623,147,546,690,637
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 623,147,546,690,637 is 39118170.
Find LCM of 623,147,546,690,637 with Prime Factorization
| 2 | 623, 147, 546, 690, 637 |
| 3 | 623, 147, 273, 345, 637 |
| 7 | 623, 49, 91, 115, 637 |
| 7 | 89, 7, 13, 115, 91 |
| 13 | 89, 1, 13, 115, 13 |
| 89, 1, 1, 115, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 7 x 13 x 89 x 1 x 1 x 115 x 1 = 39118170
Therefore, the lowest common multiple of 623,147,546,690,637 is 39118170.
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.
623 x 147 x 546 x 690 x 637 = 21977917923780
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.
623 : 1, 7, 89, 623
147 : 1, 3, 7, 21, 49, 147
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
637 : 1, 7, 13, 49, 91, 637
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 623,147,546,690,637, is 1.
Now, the common factors can be found like this.
623:7x 89
147:3x 7x 7
546:2x 3x 7x 13
690:2x 3x 5x 23
637:7x 7x 13
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 7x 7x 7x 7x 13 = 561834
Therefore, the value for common factors is 561834.
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 = 21977917923780/(1x561834)
LCM = 21977917923780/561834
LCM = 39118170
Thus, we can understand that the LCM of 623,147,546,690,637 is 39118170.
