Given numbers are 642,871,506,279,546
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,871,506,279,546 is 92098952946.
Find LCM of 642,871,506,279,546 with Prime Factorization
| 2 | 642, 871, 506, 279, 546 |
| 3 | 321, 871, 253, 279, 273 |
| 13 | 107, 871, 253, 93, 91 |
| 107, 67, 253, 93, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 107 x 67 x 253 x 93 x 7 = 92098952946
Therefore, the lowest common multiple of 642,871,506,279,546 is 92098952946.
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.
642 x 871 x 506 x 279 x 546 = 43102309978728
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
871 : 1, 13, 67, 871
506 : 1, 2, 11, 22, 23, 46, 253, 506
279 : 1, 3, 9, 31, 93, 279
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,871,506,279,546, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
871:13x 67
506:2x 11x 23
279:3x 3x 31
546:2x 3x 7x 13
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 3x 13 = 468
Therefore, the value for common factors is 468.
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 = 43102309978728/(1x468)
LCM = 43102309978728/468
LCM = 92098952946
Thus, we can understand that the LCM of 642,871,506,279,546 is 92098952946.
