Given numbers are 220, 789, 502, 154
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(220, 789) = 173580
GCD(220, 789) = ( 220 x 789 ) / 173580
= 220 / 789
= 220
Step2:
LCM(1, 502) = 502
GCD(1, 502) = ( 1 x 502 ) / 502
= 1 / 502
= 1
Step3:
LCM(1, 154) = 154
GCD(1, 154) = ( 1 x 154 ) / 154
= 1 / 154
= 1
So, Greatest Common Divisor of 220, 789, 502, 154 is 1
