Given numbers are 765, 393, 786, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(765, 393) = 100215
GCD(765, 393) = ( 765 x 393 ) / 100215
= 765 / 393
= 765
Step2:
LCM(3, 786) = 786
GCD(3, 786) = ( 3 x 786 ) / 786
= 3 / 786
= 3
Step3:
LCM(3, 781) = 2343
GCD(3, 781) = ( 3 x 781 ) / 2343
= 3 / 781
= 3
So, Greatest Common Divisor of 765, 393, 786, 781 is 1
