Given numbers are 619,629,406,655,140
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 619,629,406,655,140 is 207080222860.
Find LCM of 619,629,406,655,140 with Prime Factorization
| 2 | 619, 629, 406, 655, 140 |
| 5 | 619, 629, 203, 655, 70 |
| 7 | 619, 629, 203, 131, 14 |
| 619, 629, 29, 131, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 619 x 629 x 29 x 131 x 2 = 207080222860
Therefore, the lowest common multiple of 619,629,406,655,140 is 207080222860.
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.
619 x 629 x 406 x 655 x 140 = 14495615600200
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.
619 : 1, 619
629 : 1, 17, 37, 629
406 : 1, 2, 7, 14, 29, 58, 203, 406
655 : 1, 5, 131, 655
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,629,406,655,140, is 1.
Now, the common factors can be found like this.
619:619
629:17x 37
406:2x 7x 29
655:5x 131
140:2x 2x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7 = 70
Therefore, the value for common factors is 70.
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 = 14495615600200/(1x70)
LCM = 14495615600200/70
LCM = 207080222860
Thus, we can understand that the LCM of 619,629,406,655,140 is 207080222860.
