Given numbers are 156, 285, 764, 568
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 285) = 14820
GCD(156, 285) = ( 156 x 285 ) / 14820
= 156 / 285
= 156
Step2:
LCM(3, 764) = 2292
GCD(3, 764) = ( 3 x 764 ) / 2292
= 3 / 764
= 3
Step3:
LCM(1, 568) = 568
GCD(1, 568) = ( 1 x 568 ) / 568
= 1 / 568
= 1
So, Greatest Common Divisor of 156, 285, 764, 568 is 1
