Given numbers are 302,374,478,945,842
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 302,374,478,945,842 is 5369827748670.
Find LCM of 302,374,478,945,842 with Prime Factorization
| 2 | 302, 374, 478, 945, 842 |
| 151, 187, 239, 945, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 151 x 187 x 239 x 945 x 421 = 5369827748670
Therefore, the lowest common multiple of 302,374,478,945,842 is 5369827748670.
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.
302 x 374 x 478 x 945 x 842 = 42958621989360
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.
302 : 1, 2, 151, 302
374 : 1, 2, 11, 17, 22, 34, 187, 374
478 : 1, 2, 239, 478
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 302,374,478,945,842, is 1.
Now, the common factors can be found like this.
302:2x 151
374:2x 11x 17
478:2x 239
945:3x 3x 3x 5x 7
842:2x 421
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 2 = 8
Therefore, the value for common factors is 8.
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 = 42958621989360/(1x8)
LCM = 42958621989360/8
LCM = 5369827748670
Thus, we can understand that the LCM of 302,374,478,945,842 is 5369827748670.
