Given numbers are 690, 985, 223, 294
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 985) = 135930
GCD(690, 985) = ( 690 x 985 ) / 135930
= 690 / 985
= 690
Step2:
LCM(5, 223) = 1115
GCD(5, 223) = ( 5 x 223 ) / 1115
= 5 / 223
= 5
Step3:
LCM(1, 294) = 294
GCD(1, 294) = ( 1 x 294 ) / 294
= 1 / 294
= 1
So, Greatest Common Divisor of 690, 985, 223, 294 is 1
