The LCM of 570,849,385,781 is 881881770.
Find LCM of 570,849,385,781 with Prime Factorization
| 3 | 570, 849, 385, 781 |
| 5 | 190, 283, 385, 781 |
| 11 | 38, 283, 77, 781 |
| 38, 283, 7, 71 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 38 x 283 x 7 x 71 = 881881770
Therefore, the lowest common multiple of 570,849,385,781 is 881881770.
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.
570 x 849 x 385 x 781 = 145510492050
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.
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
849 : 1, 3, 283, 849
385 : 1, 5, 7, 11, 35, 55, 77, 385
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 570,849,385,781, is 1.
Now, the common factors can be found like this.
570:2x 3x 5x 19
849:3x 283
385:5x 7x 11
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 11 = 165
Therefore, the value for common factors is 165.
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 = 145510492050/(1x165)
LCM = 145510492050/165
LCM = 881881770
Thus, we can understand that the LCM of 570,849,385,781 is 881881770.
