Given numbers are 613,420,454,658,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 613,420,454,658,938 is 184038329580.
Find LCM of 613,420,454,658,938 with Prime Factorization
| 2 | 613, 420, 454, 658, 938 |
| 7 | 613, 210, 227, 329, 469 |
| 613, 30, 227, 47, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 613 x 30 x 227 x 47 x 67 = 184038329580
Therefore, the lowest common multiple of 613,420,454,658,938 is 184038329580.
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.
613 x 420 x 454 x 658 x 938 = 72143025195360
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.
613 : 1, 613
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
454 : 1, 2, 227, 454
658 : 1, 2, 7, 14, 47, 94, 329, 658
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 613,420,454,658,938, is 1.
Now, the common factors can be found like this.
613:613
420:2x 2x 3x 5x 7
454:2x 227
658:2x 7x 47
938:2x 7x 67
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 7x 7 = 392
Therefore, the value for common factors is 392.
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 = 72143025195360/(1x392)
LCM = 72143025195360/392
LCM = 184038329580
Thus, we can understand that the LCM of 613,420,454,658,938 is 184038329580.
