Given numbers are 821,187,880,302,630
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,187,880,302,630 is 116840188080.
Find LCM of 821,187,880,302,630 with Prime Factorization
| 2 | 821, 187, 880, 302, 630 |
| 5 | 821, 187, 440, 151, 315 |
| 11 | 821, 187, 88, 151, 63 |
| 821, 17, 8, 151, 63 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 821 x 17 x 8 x 151 x 63 = 116840188080
Therefore, the lowest common multiple of 821,187,880,302,630 is 116840188080.
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.
821 x 187 x 880 x 302 x 630 = 25704841377600
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.
821 : 1, 821
187 : 1, 11, 17, 187
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
302 : 1, 2, 151, 302
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,187,880,302,630, is 1.
Now, the common factors can be found like this.
821:821
187:11x 17
880:2x 2x 2x 2x 5x 11
302:2x 151
630:2x 3x 3x 5x 7
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 5x 11 = 220
Therefore, the value for common factors is 220.
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 = 25704841377600/(1x220)
LCM = 25704841377600/220
LCM = 116840188080
Thus, we can understand that the LCM of 821,187,880,302,630 is 116840188080.
