Given numbers are 277,221,854,782,120
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 277,221,854,782,120 is 72145458840.
Find LCM of 277,221,854,782,120 with Prime Factorization
| 2 | 277, 221, 854, 782, 120 |
| 17 | 277, 221, 427, 391, 60 |
| 277, 13, 427, 23, 60 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 277 x 13 x 427 x 23 x 60 = 72145458840
Therefore, the lowest common multiple of 277,221,854,782,120 is 72145458840.
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.
277 x 221 x 854 x 782 x 120 = 4905891201120
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.
277 : 1, 277
221 : 1, 13, 17, 221
854 : 1, 2, 7, 14, 61, 122, 427, 854
782 : 1, 2, 17, 23, 34, 46, 391, 782
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 277,221,854,782,120, is 1.
Now, the common factors can be found like this.
277:277
221:13x 17
854:2x 7x 61
782:2x 17x 23
120:2x 2x 2x 3x 5
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 17 = 68
Therefore, the value for common factors is 68.
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 = 4905891201120/(1x68)
LCM = 4905891201120/68
LCM = 72145458840
Thus, we can understand that the LCM of 277,221,854,782,120 is 72145458840.
