Given numbers are 902,510,909,505
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 902,510,909,505 is 69693030.
Find LCM of 902,510,909,505 with Prime Factorization
2 | 902, 510, 909, 505 |
3 | 451, 255, 909, 505 |
5 | 451, 85, 303, 505 |
101 | 451, 17, 303, 101 |
451, 17, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 101 x 451 x 17 x 3 x 1 = 69693030
Therefore, the lowest common multiple of 902,510,909,505 is 69693030.
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.
902 x 510 x 909 x 505 = 211169880900
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.
902 : 1, 2, 11, 22, 41, 82, 451, 902
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
909 : 1, 3, 9, 101, 303, 909
505 : 1, 5, 101, 505
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,510,909,505, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
510:2x 3x 5x 17
909:3x 3x 101
505:5x 101
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 101 = 3030
Therefore, the value for common factors is 3030.
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 = 211169880900/(1x3030)
LCM = 211169880900/3030
LCM = 69693030
Thus, we can understand that the LCM of 902,510,909,505 is 69693030.
