Given numbers are 137,780,655,959
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 137,780,655,959 is 97990620.
Find LCM of 137,780,655,959 with Prime Factorization
| 5 | 137, 780, 655, 959 |
| 137 | 137, 156, 131, 959 |
| 1, 156, 131, 7 |
Multiply the prime numbers at the bottom and the left side.
5 x 137 x 1 x 156 x 131 x 7 = 97990620
Therefore, the lowest common multiple of 137,780,655,959 is 97990620.
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.
137 x 780 x 655 x 959 = 67123574700
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.
137 : 1, 137
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
655 : 1, 5, 131, 655
959 : 1, 7, 137, 959
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 137,780,655,959, is 1.
Now, the common factors can be found like this.
137:137
780:2x 2x 3x 5x 13
655:5x 131
959:7x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 137 = 685
Therefore, the value for common factors is 685.
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 = 67123574700/(1x685)
LCM = 67123574700/685
LCM = 97990620
Thus, we can understand that the LCM of 137,780,655,959 is 97990620.
