Find LCM of 478,726,972,270,397 with Prime Factorization
2 | 478, 726, 972, 270, 397 |
3 | 239, 363, 486, 135, 397 |
3 | 239, 121, 162, 45, 397 |
3 | 239, 121, 54, 15, 397 |
239, 121, 18, 5, 397 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 239 x 121 x 18 x 5 x 397 = 55796896980
Therefore, the lowest common multiple of 478,726,972,270,397 is 55796896980.
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.
478 x 726 x 972 x 270 x 397 = 36156389243040
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.
478 : 1, 2, 239, 478
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
397 : 1, 397
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,726,972,270,397, is 1.
Now, the common factors can be found like this.
478:2x 239
726:2x 3x 11x 11
972:2x 2x 3x 3x 3x 3x 3
270:2x 3x 3x 3x 5
397:397
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 3x 3x 3 = 648
Therefore, the value for common factors is 648.
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 = 36156389243040/(1x648)
LCM = 36156389243040/648
LCM = 55796896980
Thus, we can understand that the LCM of 478,726,972,270,397 is 55796896980.
