Given numbers are 422,578,670,968,168
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 422,578,670,968,168 is 415259672520.
Find LCM of 422,578,670,968,168 with Prime Factorization
2 | 422, 578, 670, 968, 168 |
2 | 211, 289, 335, 484, 84 |
2 | 211, 289, 335, 242, 42 |
211, 289, 335, 121, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 211 x 289 x 335 x 121 x 21 = 415259672520
Therefore, the lowest common multiple of 422,578,670,968,168 is 415259672520.
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.
422 x 578 x 670 x 968 x 168 = 26576619041280
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.
422 : 1, 2, 211, 422
578 : 1, 2, 17, 34, 289, 578
670 : 1, 2, 5, 10, 67, 134, 335, 670
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,578,670,968,168, is 2.
Now, the common factors can be found like this.
422:2x 211
578:2x 17x 17
670:2x 5x 67
968:2x 2x 2x 11x 11
168:2x 2x 2x 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 2x 2x 2 = 32
Therefore, the value for common factors is 32.
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 = 26576619041280/(2x32)
LCM = 26576619041280/64
LCM = 415259672520
Thus, we can understand that the LCM of 422,578,670,968,168 is 415259672520.
