GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(202, 981) = 198162
GCD(202, 981) = ( 202 x 981 ) / 198162
= 202 / 981
= 202
Step2:
LCM(1, 478) = 478
GCD(1, 478) = ( 1 x 478 ) / 478
= 1 / 478
= 1
Step3:
LCM(1, 281) = 281
GCD(1, 281) = ( 1 x 281 ) / 281
= 1 / 281
= 1
So, Greatest Common Divisor of 202, 981, 478, 281 is 1
