Find LCM of 560,821,763,320 with Prime Factorization
| 2 | 560, 821, 763, 320 |
| 2 | 280, 821, 763, 160 |
| 2 | 140, 821, 763, 80 |
| 2 | 70, 821, 763, 40 |
| 5 | 35, 821, 763, 20 |
| 7 | 7, 821, 763, 4 |
| 1, 821, 109, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 7 x 1 x 821 x 109 x 4 = 200455360
Therefore, the lowest common multiple of 560,821,763,320 is 200455360.
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.
560 x 821 x 763 x 320 = 112255001600
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.
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
821 : 1, 821
763 : 1, 7, 109, 763
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 560,821,763,320, is 1.
Now, the common factors can be found like this.
560:2x 2x 2x 2x 5x 7
821:821
763:7x 109
320:2x 2x 2x 2x 2x 2x 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 2x 2x 5x 7 = 560
Therefore, the value for common factors is 560.
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 = 112255001600/(1x560)
LCM = 112255001600/560
LCM = 200455360
Thus, we can understand that the LCM of 560,821,763,320 is 200455360.
