Given numbers are 6,420,340,436
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 6,420,340,436 is 778260.
Find LCM of 6,420,340,436 with Prime Factorization
| 2 | 6, 420, 340, 436 |
| 2 | 3, 210, 170, 218 |
| 3 | 3, 105, 85, 109 |
| 5 | 1, 35, 85, 109 |
| 1, 7, 17, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 1 x 7 x 17 x 109 = 778260
Therefore, the lowest common multiple of 6,420,340,436 is 778260.
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.
6 x 420 x 340 x 436 = 373564800
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.
6 : 1, 2, 3, 6
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
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
436 : 1, 2, 4, 109, 218, 436
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 6,420,340,436, is 2.
Now, the common factors can be found like this.
6:2x 3
420:2x 2x 3x 5x 7
340:2x 2x 5x 17
436:2x 2x 109
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 5 = 240
Therefore, the value for common factors is 240.
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 = 373564800/(2x240)
LCM = 373564800/480
LCM = 778260
Thus, we can understand that the LCM of 6,420,340,436 is 778260.
