Given numbers are 660, 128, 303, 897
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 128) = 21120
GCD(660, 128) = ( 660 x 128 ) / 21120
= 660 / 128
= 660
Step2:
LCM(4, 303) = 1212
GCD(4, 303) = ( 4 x 303 ) / 1212
= 4 / 303
= 4
Step3:
LCM(1, 897) = 897
GCD(1, 897) = ( 1 x 897 ) / 897
= 1 / 897
= 1
So, Greatest Common Divisor of 660, 128, 303, 897 is 1
