Find LCM of 440,690,161,252,931 with Prime Factorization
2 | 440, 690, 161, 252, 931 |
2 | 220, 345, 161, 126, 931 |
3 | 110, 345, 161, 63, 931 |
5 | 110, 115, 161, 21, 931 |
7 | 22, 23, 161, 21, 931 |
23 | 22, 23, 23, 3, 133 |
22, 1, 1, 3, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 23 x 22 x 1 x 1 x 3 x 133 = 84795480
Therefore, the lowest common multiple of 440,690,161,252,931 is 84795480.
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.
440 x 690 x 161 x 252 x 931 = 11467740715200
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.
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
161 : 1, 7, 23, 161
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,690,161,252,931, is 1.
Now, the common factors can be found like this.
440:2x 2x 2x 5x 11
690:2x 3x 5x 23
161:7x 23
252:2x 2x 3x 3x 7
931:7x 7x 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 3x 5x 7x 7x 23 = 135240
Therefore, the value for common factors is 135240.
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 = 11467740715200/(1x135240)
LCM = 11467740715200/135240
LCM = 84795480
Thus, we can understand that the LCM of 440,690,161,252,931 is 84795480.
