Given numbers are 122, 858, 690, 177
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(122, 858) = 52338
GCD(122, 858) = ( 122 x 858 ) / 52338
= 122 / 858
= 122
Step2:
LCM(2, 690) = 690
GCD(2, 690) = ( 2 x 690 ) / 690
= 2 / 690
= 2
Step3:
LCM(2, 177) = 354
GCD(2, 177) = ( 2 x 177 ) / 354
= 2 / 177
= 2
So, Greatest Common Divisor of 122, 858, 690, 177 is 1
