Given numbers are 653,658,271,198,210
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 653,658,271,198,210 is 57638618730.
Find LCM of 653,658,271,198,210 with Prime Factorization
| 2 | 653, 658, 271, 198, 210 |
| 3 | 653, 329, 271, 99, 105 |
| 7 | 653, 329, 271, 33, 35 |
| 653, 47, 271, 33, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 653 x 47 x 271 x 33 x 5 = 57638618730
Therefore, the lowest common multiple of 653,658,271,198,210 is 57638618730.
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.
653 x 658 x 271 x 198 x 210 = 4841643973320
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.
653 : 1, 653
658 : 1, 2, 7, 14, 47, 94, 329, 658
271 : 1, 271
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 653,658,271,198,210, is 1.
Now, the common factors can be found like this.
653:653
658:2x 7x 47
271:271
198:2x 3x 3x 11
210:2x 3x 5x 7
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 7 = 84
Therefore, the value for common factors is 84.
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 = 4841643973320/(1x84)
LCM = 4841643973320/84
LCM = 57638618730
Thus, we can understand that the LCM of 653,658,271,198,210 is 57638618730.
