Given numbers are 722,780,685,253,212
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 722,780,685,253,212 is 517271752140.
Find LCM of 722,780,685,253,212 with Prime Factorization
| 2 | 722, 780, 685, 253, 212 |
| 2 | 361, 390, 685, 253, 106 |
| 5 | 361, 195, 685, 253, 53 |
| 361, 39, 137, 253, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 361 x 39 x 137 x 253 x 53 = 517271752140
Therefore, the lowest common multiple of 722,780,685,253,212 is 517271752140.
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.
722 x 780 x 685 x 253 x 212 = 20690870085600
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.
722 : 1, 2, 19, 38, 361, 722
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
685 : 1, 5, 137, 685
253 : 1, 11, 23, 253
212 : 1, 2, 4, 53, 106, 212
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,780,685,253,212, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
780:2x 2x 3x 5x 13
685:5x 137
253:11x 23
212:2x 2x 53
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 5 = 40
Therefore, the value for common factors is 40.
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 = 20690870085600/(1x40)
LCM = 20690870085600/40
LCM = 517271752140
Thus, we can understand that the LCM of 722,780,685,253,212 is 517271752140.
