GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(252, 980) = 8820
GCD(252, 980) = ( 252 x 980 ) / 8820
= 252 / 980
= 252
Step2:
LCM(28, 777) = 3108
GCD(28, 777) = ( 28 x 777 ) / 3108
= 28 / 777
= 28
Step3:
LCM(7, 156) = 1092
GCD(7, 156) = ( 7 x 156 ) / 1092
= 7 / 156
= 7
So, Greatest Common Divisor of 252, 980, 777, 156 is 1
