Find LCM of 219,420,693,754,969 with Prime Factorization
2 | 219, 420, 693, 754, 969 |
3 | 219, 210, 693, 377, 969 |
7 | 73, 70, 231, 377, 323 |
73, 10, 33, 377, 323 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 73 x 10 x 33 x 377 x 323 = 123205462380
Therefore, the lowest common multiple of 219,420,693,754,969 is 123205462380.
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.
219 x 420 x 693 x 754 x 969 = 46571664779640
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.
219 : 1, 3, 73, 219
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
754 : 1, 2, 13, 26, 29, 58, 377, 754
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 219,420,693,754,969, is 1.
Now, the common factors can be found like this.
219:3x 73
420:2x 2x 3x 5x 7
693:3x 3x 7x 11
754:2x 13x 29
969:3x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 7 = 378
Therefore, the value for common factors is 378.
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 = 46571664779640/(1x378)
LCM = 46571664779640/378
LCM = 123205462380
Thus, we can understand that the LCM of 219,420,693,754,969 is 123205462380.
