Given numbers are 421,425,230,620,688
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,425,230,620,688 is 87770585200.
Find LCM of 421,425,230,620,688 with Prime Factorization
2 | 421, 425, 230, 620, 688 |
2 | 421, 425, 115, 310, 344 |
5 | 421, 425, 115, 155, 172 |
421, 85, 23, 31, 172 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 421 x 85 x 23 x 31 x 172 = 87770585200
Therefore, the lowest common multiple of 421,425,230,620,688 is 87770585200.
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.
421 x 425 x 230 x 620 x 688 = 17554117040000
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.
421 : 1, 421
425 : 1, 5, 17, 25, 85, 425
230 : 1, 2, 5, 10, 23, 46, 115, 230
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,425,230,620,688, is 1.
Now, the common factors can be found like this.
421:421
425:5x 5x 17
230:2x 5x 23
620:2x 2x 5x 31
688:2x 2x 2x 2x 43
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 5x 5 = 200
Therefore, the value for common factors is 200.
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 = 17554117040000/(1x200)
LCM = 17554117040000/200
LCM = 87770585200
Thus, we can understand that the LCM of 421,425,230,620,688 is 87770585200.
