Given numbers are 631,697,532,420,163
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 631,697,532,420,163 is 572074557180.
Find LCM of 631,697,532,420,163 with Prime Factorization
| 2 | 631, 697, 532, 420, 163 |
| 2 | 631, 697, 266, 210, 163 |
| 7 | 631, 697, 133, 105, 163 |
| 631, 697, 19, 15, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 631 x 697 x 19 x 15 x 163 = 572074557180
Therefore, the lowest common multiple of 631,697,532,420,163 is 572074557180.
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.
631 x 697 x 532 x 420 x 163 = 16018087601040
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.
631 : 1, 631
697 : 1, 17, 41, 697
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
163 : 1, 163
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,697,532,420,163, is 1.
Now, the common factors can be found like this.
631:631
697:17x 41
532:2x 2x 7x 19
420:2x 2x 3x 5x 7
163:163
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 7 = 28
Therefore, the value for common factors is 28.
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 = 16018087601040/(1x28)
LCM = 16018087601040/28
LCM = 572074557180
Thus, we can understand that the LCM of 631,697,532,420,163 is 572074557180.
