Find LCM of 781,377,190,820,741 with Prime Factorization
2 | 781, 377, 190, 820, 741 |
5 | 781, 377, 95, 410, 741 |
13 | 781, 377, 19, 82, 741 |
19 | 781, 29, 19, 82, 57 |
781, 29, 1, 82, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 19 x 781 x 29 x 1 x 82 x 3 = 13761985380
Therefore, the lowest common multiple of 781,377,190,820,741 is 13761985380.
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.
781 x 377 x 190 x 820 x 741 = 33992103888600
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.
781 : 1, 11, 71, 781
377 : 1, 13, 29, 377
190 : 1, 2, 5, 10, 19, 38, 95, 190
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
741 : 1, 3, 13, 19, 39, 57, 247, 741
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,377,190,820,741, is 1.
Now, the common factors can be found like this.
781:11x 71
377:13x 29
190:2x 5x 19
820:2x 2x 5x 41
741:3x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13x 19 = 2470
Therefore, the value for common factors is 2470.
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 = 33992103888600/(1x2470)
LCM = 33992103888600/2470
LCM = 13761985380
Thus, we can understand that the LCM of 781,377,190,820,741 is 13761985380.
