The LCM of 525,380,616,420 is 877800.
Find LCM of 525,380,616,420 with Prime Factorization
| 2 | 525, 380, 616, 420 |
| 2 | 525, 190, 308, 210 |
| 3 | 525, 95, 154, 105 |
| 5 | 175, 95, 154, 35 |
| 7 | 7, 19, 154, 35 |
| 1, 19, 22, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 1 x 19 x 22 x 5 = 877800
Therefore, the lowest common multiple of 525,380,616,420 is 877800.
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.
525 x 380 x 616 x 420 = 51614640000
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.
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 525,380,616,420, is 1.
Now, the common factors can be found like this.
525:3x 5x 5x 7
380:2x 2x 5x 19
616:2x 2x 2x 7x 11
420:2x 2x 3x 5x 7
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 5x 5x 7x 7 = 58800
Therefore, the value for common factors is 58800.
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 = 51614640000/(1x58800)
LCM = 51614640000/58800
LCM = 877800
Thus, we can understand that the LCM of 525,380,616,420 is 877800.
