Given numbers are 156, 280, 279, 485
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 280) = 10920
GCD(156, 280) = ( 156 x 280 ) / 10920
= 156 / 280
= 156
Step2:
LCM(4, 279) = 1116
GCD(4, 279) = ( 4 x 279 ) / 1116
= 4 / 279
= 4
Step3:
LCM(1, 485) = 485
GCD(1, 485) = ( 1 x 485 ) / 485
= 1 / 485
= 1
So, Greatest Common Divisor of 156, 280, 279, 485 is 1
