Given numbers are 880, 685, 138, 324
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(880, 685) = 120560
GCD(880, 685) = ( 880 x 685 ) / 120560
= 880 / 685
= 880
Step2:
LCM(5, 138) = 690
GCD(5, 138) = ( 5 x 138 ) / 690
= 5 / 138
= 5
Step3:
LCM(1, 324) = 324
GCD(1, 324) = ( 1 x 324 ) / 324
= 1 / 324
= 1
So, Greatest Common Divisor of 880, 685, 138, 324 is 1
