Given numbers are 189, 764, 277, 456
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(189, 764) = 144396
GCD(189, 764) = ( 189 x 764 ) / 144396
= 189 / 764
= 189
Step2:
LCM(1, 277) = 277
GCD(1, 277) = ( 1 x 277 ) / 277
= 1 / 277
= 1
Step3:
LCM(1, 456) = 456
GCD(1, 456) = ( 1 x 456 ) / 456
= 1 / 456
= 1
So, Greatest Common Divisor of 189, 764, 277, 456 is 1
