Given numbers are 281,153,855,971,279
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 281,153,855,971,279 is 122942567835.
Find LCM of 281,153,855,971,279 with Prime Factorization
3 | 281, 153, 855, 971, 279 |
3 | 281, 51, 285, 971, 93 |
281, 17, 95, 971, 31 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 281 x 17 x 95 x 971 x 31 = 122942567835
Therefore, the lowest common multiple of 281,153,855,971,279 is 122942567835.
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.
281 x 153 x 855 x 971 x 279 = 9958347994635
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.
281 : 1, 281
153 : 1, 3, 9, 17, 51, 153
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
971 : 1, 971
279 : 1, 3, 9, 31, 93, 279
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,153,855,971,279, is 1.
Now, the common factors can be found like this.
281:281
153:3x 3x 17
855:3x 3x 5x 19
971:971
279:3x 3x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3 = 81
Therefore, the value for common factors is 81.
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 = 9958347994635/(1x81)
LCM = 9958347994635/81
LCM = 122942567835
Thus, we can understand that the LCM of 281,153,855,971,279 is 122942567835.
