Given numbers are 778, 641, 485, 295
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(778, 641) = 498698
GCD(778, 641) = ( 778 x 641 ) / 498698
= 778 / 641
= 778
Step2:
LCM(1, 485) = 485
GCD(1, 485) = ( 1 x 485 ) / 485
= 1 / 485
= 1
Step3:
LCM(1, 295) = 295
GCD(1, 295) = ( 1 x 295 ) / 295
= 1 / 295
= 1
So, Greatest Common Divisor of 778, 641, 485, 295 is 1
