Given numbers are 620,964,704,297,254
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 620,964,704,297,254 is 90175567680.
Find LCM of 620,964,704,297,254 with Prime Factorization
| 2 | 620, 964, 704, 297, 254 |
| 2 | 310, 482, 352, 297, 127 |
| 11 | 155, 241, 176, 297, 127 |
| 155, 241, 16, 27, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 155 x 241 x 16 x 27 x 127 = 90175567680
Therefore, the lowest common multiple of 620,964,704,297,254 is 90175567680.
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.
620 x 964 x 704 x 297 x 254 = 31741799823360
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
964 : 1, 2, 4, 241, 482, 964
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
297 : 1, 3, 9, 11, 27, 33, 99, 297
254 : 1, 2, 127, 254
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,964,704,297,254, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
964:2x 2x 241
704:2x 2x 2x 2x 2x 2x 11
297:3x 3x 3x 11
254:2x 127
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 2x 2x 11 = 352
Therefore, the value for common factors is 352.
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 = 31741799823360/(1x352)
LCM = 31741799823360/352
LCM = 90175567680
Thus, we can understand that the LCM of 620,964,704,297,254 is 90175567680.
