Find LCM of 665,532,892,690,152 with Prime Factorization
| 2 | 665, 532, 892, 690, 152 |
| 2 | 665, 266, 446, 345, 76 |
| 5 | 665, 133, 223, 345, 38 |
| 7 | 133, 133, 223, 69, 38 |
| 19 | 19, 19, 223, 69, 38 |
| 1, 1, 223, 69, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 19 x 1 x 1 x 223 x 69 x 2 = 81858840
Therefore, the lowest common multiple of 665,532,892,690,152 is 81858840.
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.
665 x 532 x 892 x 690 x 152 = 33097166188800
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
892 : 1, 2, 4, 223, 446, 892
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
152 : 1, 2, 4, 8, 19, 38, 76, 152
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,532,892,690,152, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
532:2x 2x 7x 19
892:2x 2x 223
690:2x 3x 5x 23
152:2x 2x 2x 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 2x 2x 2x 2x 5x 7x 19x 19 = 404320
Therefore, the value for common factors is 404320.
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 = 33097166188800/(1x404320)
LCM = 33097166188800/404320
LCM = 81858840
Thus, we can understand that the LCM of 665,532,892,690,152 is 81858840.
