Given numbers are 632,690,978,710,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 632,690,978,710,905 is 456731222520.
Find LCM of 632,690,978,710,905 with Prime Factorization
| 2 | 632, 690, 978, 710, 905 |
| 3 | 316, 345, 489, 355, 905 |
| 5 | 316, 115, 163, 355, 905 |
| 316, 23, 163, 71, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 316 x 23 x 163 x 71 x 181 = 456731222520
Therefore, the lowest common multiple of 632,690,978,710,905 is 456731222520.
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.
632 x 690 x 978 x 710 x 905 = 274038733512000
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.
632 : 1, 2, 4, 8, 79, 158, 316, 632
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
978 : 1, 2, 3, 6, 163, 326, 489, 978
710 : 1, 2, 5, 10, 71, 142, 355, 710
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 632,690,978,710,905, is 1.
Now, the common factors can be found like this.
632:2x 2x 2x 79
690:2x 3x 5x 23
978:2x 3x 163
710:2x 5x 71
905:5x 181
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 5x 5 = 600
Therefore, the value for common factors is 600.
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 = 274038733512000/(1x600)
LCM = 274038733512000/600
LCM = 456731222520
Thus, we can understand that the LCM of 632,690,978,710,905 is 456731222520.
