Given numbers are 690, 303, 133, 217
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 303) = 69690
GCD(690, 303) = ( 690 x 303 ) / 69690
= 690 / 303
= 690
Step2:
LCM(3, 133) = 399
GCD(3, 133) = ( 3 x 133 ) / 399
= 3 / 133
= 3
Step3:
LCM(1, 217) = 217
GCD(1, 217) = ( 1 x 217 ) / 217
= 1 / 217
= 1
So, Greatest Common Divisor of 690, 303, 133, 217 is 1
