Given numbers are 252, 520, 865, 180
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(252, 520) = 32760
GCD(252, 520) = ( 252 x 520 ) / 32760
= 252 / 520
= 252
Step2:
LCM(4, 865) = 3460
GCD(4, 865) = ( 4 x 865 ) / 3460
= 4 / 865
= 4
Step3:
LCM(1, 180) = 180
GCD(1, 180) = ( 1 x 180 ) / 180
= 1 / 180
= 1
So, Greatest Common Divisor of 252, 520, 865, 180 is 1
