Given numbers are 205, 342, 762, 220
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(205, 342) = 70110
GCD(205, 342) = ( 205 x 342 ) / 70110
= 205 / 342
= 205
Step2:
LCM(1, 762) = 762
GCD(1, 762) = ( 1 x 762 ) / 762
= 1 / 762
= 1
Step3:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
So, Greatest Common Divisor of 205, 342, 762, 220 is 1
