Given numbers are 981, 201, 502, 478
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 201) = 65727
GCD(981, 201) = ( 981 x 201 ) / 65727
= 981 / 201
= 981
Step2:
LCM(3, 502) = 1506
GCD(3, 502) = ( 3 x 502 ) / 1506
= 3 / 502
= 3
Step3:
LCM(1, 478) = 478
GCD(1, 478) = ( 1 x 478 ) / 478
= 1 / 478
= 1
So, Greatest Common Divisor of 981, 201, 502, 478 is 1
