Given numbers are 374,620,391,225
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 374,620,391,225 is 119997900.
Find LCM of 374,620,391,225 with Prime Factorization
2 | 374, 620, 391, 225 |
5 | 187, 310, 391, 225 |
17 | 187, 62, 391, 45 |
11, 62, 23, 45 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 11 x 62 x 23 x 45 = 119997900
Therefore, the lowest common multiple of 374,620,391,225 is 119997900.
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.
374 x 620 x 391 x 225 = 20399643000
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.
374 : 1, 2, 11, 17, 22, 34, 187, 374
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
391 : 1, 17, 23, 391
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 374,620,391,225, is 1.
Now, the common factors can be found like this.
374:2x 11x 17
620:2x 2x 5x 31
391:17x 23
225:3x 3x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 17 = 170
Therefore, the value for common factors is 170.
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 = 20399643000/(1x170)
LCM = 20399643000/170
LCM = 119997900
Thus, we can understand that the LCM of 374,620,391,225 is 119997900.
