Given numbers are 263, 853, 129, 645
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(263, 853) = 224339
GCD(263, 853) = ( 263 x 853 ) / 224339
= 263 / 853
= 263
Step2:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
Step3:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
So, Greatest Common Divisor of 263, 853, 129, 645 is 1
