Given numbers are 778, 860, 145, 255
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(778, 860) = 334540
GCD(778, 860) = ( 778 x 860 ) / 334540
= 778 / 860
= 778
Step2:
LCM(2, 145) = 290
GCD(2, 145) = ( 2 x 145 ) / 290
= 2 / 145
= 2
Step3:
LCM(1, 255) = 255
GCD(1, 255) = ( 1 x 255 ) / 255
= 1 / 255
= 1
So, Greatest Common Divisor of 778, 860, 145, 255 is 1
