Find LCM of 425,437,403,918,420 with Prime Factorization
2 | 425, 437, 403, 918, 420 |
3 | 425, 437, 403, 459, 210 |
5 | 425, 437, 403, 153, 70 |
17 | 85, 437, 403, 153, 14 |
5, 437, 403, 9, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 5 x 437 x 403 x 9 x 14 = 56584464300
Therefore, the lowest common multiple of 425,437,403,918,420 is 56584464300.
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.
425 x 437 x 403 x 918 x 420 = 28858076793000
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.
425 : 1, 5, 17, 25, 85, 425
437 : 1, 19, 23, 437
403 : 1, 13, 31, 403
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 425,437,403,918,420, is 1.
Now, the common factors can be found like this.
425:5x 5x 17
437:19x 23
403:13x 31
918:2x 3x 3x 3x 17
420:2x 2x 3x 5x 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 3x 5x 17 = 510
Therefore, the value for common factors is 510.
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 = 28858076793000/(1x510)
LCM = 28858076793000/510
LCM = 56584464300
Thus, we can understand that the LCM of 425,437,403,918,420 is 56584464300.
