Find LCM of 780,186,655,255,178 with Prime Factorization
2 | 780, 186, 655, 255, 178 |
3 | 390, 93, 655, 255, 89 |
5 | 130, 31, 655, 85, 89 |
26, 31, 131, 17, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 26 x 31 x 131 x 17 x 89 = 4792548540
Therefore, the lowest common multiple of 780,186,655,255,178 is 4792548540.
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.
780 x 186 x 655 x 255 x 178 = 4313293686000
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.
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
186 : 1, 2, 3, 6, 31, 62, 93, 186
655 : 1, 5, 131, 655
255 : 1, 3, 5, 15, 17, 51, 85, 255
178 : 1, 2, 89, 178
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,186,655,255,178, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
186:2x 3x 31
655:5x 131
255:3x 5x 17
178:2x 89
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 3x 3x 5x 5 = 900
Therefore, the value for common factors is 900.
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 = 4313293686000/(1x900)
LCM = 4313293686000/900
LCM = 4792548540
Thus, we can understand that the LCM of 780,186,655,255,178 is 4792548540.
