Given numbers are 221,770,989,383,538
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 221,770,989,383,538 is 17339251439510.
Find LCM of 221,770,989,383,538 with Prime Factorization
2 | 221, 770, 989, 383, 538 |
221, 385, 989, 383, 269 |
Multiply the prime numbers at the bottom and the left side.
2 x 221 x 385 x 989 x 383 x 269 = 17339251439510
Therefore, the lowest common multiple of 221,770,989,383,538 is 17339251439510.
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.
221 x 770 x 989 x 383 x 538 = 34678502879020
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.
221 : 1, 13, 17, 221
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
989 : 1, 23, 43, 989
383 : 1, 383
538 : 1, 2, 269, 538
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,770,989,383,538, is 1.
Now, the common factors can be found like this.
221:13x 17
770:2x 5x 7x 11
989:23x 43
383:383
538:2x 269
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 34678502879020/(1x2)
LCM = 34678502879020/2
LCM = 17339251439510
Thus, we can understand that the LCM of 221,770,989,383,538 is 17339251439510.
