Given numbers are 630,191,221,455,803
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 630,191,221,455,803 is 21354122790.
Find LCM of 630,191,221,455,803 with Prime Factorization
5 | 630, 191, 221, 455, 803 |
7 | 126, 191, 221, 91, 803 |
13 | 18, 191, 221, 13, 803 |
18, 191, 17, 1, 803 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 13 x 18 x 191 x 17 x 1 x 803 = 21354122790
Therefore, the lowest common multiple of 630,191,221,455,803 is 21354122790.
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.
630 x 191 x 221 x 455 x 803 = 9716125869450
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.
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
191 : 1, 191
221 : 1, 13, 17, 221
455 : 1, 5, 7, 13, 35, 65, 91, 455
803 : 1, 11, 73, 803
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,191,221,455,803, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
191:191
221:13x 17
455:5x 7x 13
803:11x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 13 = 455
Therefore, the value for common factors is 455.
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 = 9716125869450/(1x455)
LCM = 9716125869450/455
LCM = 21354122790
Thus, we can understand that the LCM of 630,191,221,455,803 is 21354122790.
