Given numbers are 619,454,420,963,342
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 619,454,420,963,342 is 359935290540.
Find LCM of 619,454,420,963,342 with Prime Factorization
| 2 | 619, 454, 420, 963, 342 |
| 3 | 619, 227, 210, 963, 171 |
| 3 | 619, 227, 70, 321, 57 |
| 619, 227, 70, 107, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 619 x 227 x 70 x 107 x 19 = 359935290540
Therefore, the lowest common multiple of 619,454,420,963,342 is 359935290540.
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.
619 x 454 x 420 x 963 x 342 = 38873011378320
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.
619 : 1, 619
454 : 1, 2, 227, 454
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
963 : 1, 3, 9, 107, 321, 963
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,454,420,963,342, is 1.
Now, the common factors can be found like this.
619:619
454:2x 227
420:2x 2x 3x 5x 7
963:3x 3x 107
342:2x 3x 3x 19
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 3 = 108
Therefore, the value for common factors is 108.
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 = 38873011378320/(1x108)
LCM = 38873011378320/108
LCM = 359935290540
Thus, we can understand that the LCM of 619,454,420,963,342 is 359935290540.
