Given numbers are 660, 209, 807, 765
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 209) = 12540
GCD(660, 209) = ( 660 x 209 ) / 12540
= 660 / 209
= 660
Step2:
LCM(11, 807) = 8877
GCD(11, 807) = ( 11 x 807 ) / 8877
= 11 / 807
= 11
Step3:
LCM(1, 765) = 765
GCD(1, 765) = ( 1 x 765 ) / 765
= 1 / 765
= 1
So, Greatest Common Divisor of 660, 209, 807, 765 is 1
