Given numbers are 270, 215, 505, 688
The list of prime factors of all numbers are
Prime factors of 270 are 2 x 3 x 3 x 3 x 5
Prime factors of 215 are 5 x 43
Prime factors of 505 are 5 x 101
Prime factors of 688 are 2 x 2 x 2 x 2 x 43
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 270, 215, 505, 688
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(270, 215) = 11610
GCD(270, 215) = ( 270 x 215 ) / 11610
= 270 / 215
= 270
Step2:
LCM(5, 505) = 505
GCD(5, 505) = ( 5 x 505 ) / 505
= 5 / 505
= 5
Step3:
LCM(5, 688) = 3440
GCD(5, 688) = ( 5 x 688 ) / 3440
= 5 / 688
= 5
So, Greatest Common Divisor of 270, 215, 505, 688 is 1
