Given numbers are 746,780,660,611
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 746,780,660,611 is 150415980.
Find LCM of 746,780,660,611 with Prime Factorization
| 2 | 746, 780, 660, 611 |
| 2 | 373, 390, 330, 611 |
| 3 | 373, 195, 165, 611 |
| 5 | 373, 65, 55, 611 |
| 13 | 373, 13, 11, 611 |
| 373, 1, 11, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 373 x 1 x 11 x 47 = 150415980
Therefore, the lowest common multiple of 746,780,660,611 is 150415980.
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.
746 x 780 x 660 x 611 = 234648928800
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.
746 : 1, 2, 373, 746
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
611 : 1, 13, 47, 611
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 746,780,660,611, is 1.
Now, the common factors can be found like this.
746:2x 373
780:2x 2x 3x 5x 13
660:2x 2x 3x 5x 11
611:13x 47
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 13 = 1560
Therefore, the value for common factors is 1560.
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 = 234648928800/(1x1560)
LCM = 234648928800/1560
LCM = 150415980
Thus, we can understand that the LCM of 746,780,660,611 is 150415980.
