Given numbers are 681,702,624,618,155
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,702,624,618,155 is 20352692880.
Find LCM of 681,702,624,618,155 with Prime Factorization
| 2 | 681, 702, 624, 618, 155 |
| 3 | 681, 351, 312, 309, 155 |
| 13 | 227, 117, 104, 103, 155 |
| 227, 9, 8, 103, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 227 x 9 x 8 x 103 x 155 = 20352692880
Therefore, the lowest common multiple of 681,702,624,618,155 is 20352692880.
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.
681 x 702 x 624 x 618 x 155 = 28575180803520
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.
681 : 1, 3, 227, 681
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
618 : 1, 2, 3, 6, 103, 206, 309, 618
155 : 1, 5, 31, 155
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,702,624,618,155, is 1.
Now, the common factors can be found like this.
681:3x 227
702:2x 3x 3x 3x 13
624:2x 2x 2x 2x 3x 13
618:2x 3x 103
155:5x 31
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 3x 3x 3x 13 = 1404
Therefore, the value for common factors is 1404.
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 = 28575180803520/(1x1404)
LCM = 28575180803520/1404
LCM = 20352692880
Thus, we can understand that the LCM of 681,702,624,618,155 is 20352692880.
