Given numbers are 420,708,423,319,292
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 420,708,423,319,292 is 81364312260.
Find LCM of 420,708,423,319,292 with Prime Factorization
| 2 | 420, 708, 423, 319, 292 |
| 2 | 210, 354, 423, 319, 146 |
| 3 | 105, 177, 423, 319, 73 |
| 35, 59, 141, 319, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 35 x 59 x 141 x 319 x 73 = 81364312260
Therefore, the lowest common multiple of 420,708,423,319,292 is 81364312260.
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.
420 x 708 x 423 x 319 x 292 = 11716460965440
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.
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
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
423 : 1, 3, 9, 47, 141, 423
319 : 1, 11, 29, 319
292 : 1, 2, 4, 73, 146, 292
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,708,423,319,292, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
708:2x 2x 3x 59
423:3x 3x 47
319:11x 29
292:2x 2x 73
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 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 11716460965440/(1x144)
LCM = 11716460965440/144
LCM = 81364312260
Thus, we can understand that the LCM of 420,708,423,319,292 is 81364312260.
