Find LCM of 640,161,504,781,114 with Prime Factorization
2 | 640, 161, 504, 781, 114 |
2 | 320, 161, 252, 781, 57 |
2 | 160, 161, 126, 781, 57 |
3 | 80, 161, 63, 781, 57 |
7 | 80, 161, 21, 781, 19 |
80, 23, 3, 781, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 80 x 23 x 3 x 781 x 19 = 13761095040
Therefore, the lowest common multiple of 640,161,504,781,114 is 13761095040.
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.
640 x 161 x 504 x 781 x 114 = 4623727933440
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.
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
161 : 1, 7, 23, 161
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
781 : 1, 11, 71, 781
114 : 1, 2, 3, 6, 19, 38, 57, 114
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,161,504,781,114, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
161:7x 23
504:2x 2x 2x 3x 3x 7
781:11x 71
114:2x 3x 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 2x 2x 2x 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 4623727933440/(1x336)
LCM = 4623727933440/336
LCM = 13761095040
Thus, we can understand that the LCM of 640,161,504,781,114 is 13761095040.
