GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(524, 196) = 25676
GCD(524, 196) = ( 524 x 196 ) / 25676
= 524 / 196
= 524
Step2:
LCM(4, 421) = 1684
GCD(4, 421) = ( 4 x 421 ) / 1684
= 4 / 421
= 4
Step3:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
So, Greatest Common Divisor of 524, 196, 421, 981 is 1
