Given numbers are 281,430,870,916,551
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 281,430,870,916,551 is 91477251420.
Find LCM of 281,430,870,916,551 with Prime Factorization
2 | 281, 430, 870, 916, 551 |
5 | 281, 215, 435, 458, 551 |
29 | 281, 43, 87, 458, 551 |
281, 43, 3, 458, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 29 x 281 x 43 x 3 x 458 x 19 = 91477251420
Therefore, the lowest common multiple of 281,430,870,916,551 is 91477251420.
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 430 x 870 x 916 x 551 = 53056805823600
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
430 : 1, 2, 5, 10, 43, 86, 215, 430
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
916 : 1, 2, 4, 229, 458, 916
551 : 1, 19, 29, 551
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,430,870,916,551, is 1.
Now, the common factors can be found like this.
281:281
430:2x 5x 43
870:2x 3x 5x 29
916:2x 2x 229
551:19x 29
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 5x 29 = 580
Therefore, the value for common factors is 580.
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 = 53056805823600/(1x580)
LCM = 53056805823600/580
LCM = 91477251420
Thus, we can understand that the LCM of 281,430,870,916,551 is 91477251420.
