Find LCM of 605,980,415,497,756 with Prime Factorization
2 | 605, 980, 415, 497, 756 |
2 | 605, 490, 415, 497, 378 |
5 | 605, 245, 415, 497, 189 |
7 | 121, 49, 83, 497, 189 |
121, 7, 83, 71, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 121 x 7 x 83 x 71 x 27 = 18867382380
Therefore, the lowest common multiple of 605,980,415,497,756 is 18867382380.
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.
605 x 980 x 415 x 497 x 756 = 92450173662000
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.
605 : 1, 5, 11, 55, 121, 605
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
415 : 1, 5, 83, 415
497 : 1, 7, 71, 497
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,980,415,497,756, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
980:2x 2x 5x 7x 7
415:5x 83
497:7x 71
756:2x 2x 3x 3x 3x 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 5x 7x 7 = 4900
Therefore, the value for common factors is 4900.
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 = 92450173662000/(1x4900)
LCM = 92450173662000/4900
LCM = 18867382380
Thus, we can understand that the LCM of 605,980,415,497,756 is 18867382380.
