Given numbers are 256, 660, 271, 445
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(256, 660) = 42240
GCD(256, 660) = ( 256 x 660 ) / 42240
= 256 / 660
= 256
Step2:
LCM(4, 271) = 1084
GCD(4, 271) = ( 4 x 271 ) / 1084
= 4 / 271
= 4
Step3:
LCM(1, 445) = 445
GCD(1, 445) = ( 1 x 445 ) / 445
= 1 / 445
= 1
So, Greatest Common Divisor of 256, 660, 271, 445 is 1
