Given numbers are 780,127,172,301
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 780,127,172,301 is 29817060.
Find LCM of 780,127,172,301 with Prime Factorization
2 | 780, 127, 172, 301 |
2 | 390, 127, 86, 301 |
43 | 195, 127, 43, 301 |
195, 127, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 195 x 127 x 1 x 7 = 29817060
Therefore, the lowest common multiple of 780,127,172,301 is 29817060.
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 127 x 172 x 301 = 5128534320
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
127 : 1, 127
172 : 1, 2, 4, 43, 86, 172
301 : 1, 7, 43, 301
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,127,172,301, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
127:127
172:2x 2x 43
301:7x 43
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 43 = 172
Therefore, the value for common factors is 172.
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 = 5128534320/(1x172)
LCM = 5128534320/172
LCM = 29817060
Thus, we can understand that the LCM of 780,127,172,301 is 29817060.
