Given numbers are 420,312,605,625
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 420,312,605,625 is 165165000.
Find LCM of 420,312,605,625 with Prime Factorization
2 | 420, 312, 605, 625 |
2 | 210, 156, 605, 625 |
3 | 105, 78, 605, 625 |
5 | 35, 26, 605, 625 |
7, 26, 121, 125 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 26 x 121 x 125 = 165165000
Therefore, the lowest common multiple of 420,312,605,625 is 165165000.
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 312 x 605 x 625 = 49549500000
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
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
605 : 1, 5, 11, 55, 121, 605
625 : 1, 5, 25, 125, 625
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,312,605,625, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
312:2x 2x 2x 3x 13
605:5x 11x 11
625:5x 5x 5x 5
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 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 49549500000/(1x300)
LCM = 49549500000/300
LCM = 165165000
Thus, we can understand that the LCM of 420,312,605,625 is 165165000.
