Given numbers are 985, 909, 981, 281
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(985, 909) = 895365
GCD(985, 909) = ( 985 x 909 ) / 895365
= 985 / 909
= 985
Step2:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
Step3:
LCM(1, 281) = 281
GCD(1, 281) = ( 1 x 281 ) / 281
= 1 / 281
= 1
So, Greatest Common Divisor of 985, 909, 981, 281 is 1
