Given numbers are 882,264,781,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 882,264,781,220 is 13776840.
Find LCM of 882,264,781,220 with Prime Factorization
| 2 | 882, 264, 781, 220 |
| 2 | 441, 132, 781, 110 |
| 3 | 441, 66, 781, 55 |
| 11 | 147, 22, 781, 55 |
| 147, 2, 71, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 147 x 2 x 71 x 5 = 13776840
Therefore, the lowest common multiple of 882,264,781,220 is 13776840.
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.
882 x 264 x 781 x 220 = 40007943360
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.
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
264 : 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264
781 : 1, 11, 71, 781
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 882,264,781,220, is 1.
Now, the common factors can be found like this.
882:2x 3x 3x 7x 7
264:2x 2x 2x 3x 11
781:11x 71
220:2x 2x 5x 11
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 3x 11x 11 = 2904
Therefore, the value for common factors is 2904.
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 = 40007943360/(1x2904)
LCM = 40007943360/2904
LCM = 13776840
Thus, we can understand that the LCM of 882,264,781,220 is 13776840.
