Given numbers are 550, 778, 235, 805
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(550, 778) = 213950
GCD(550, 778) = ( 550 x 778 ) / 213950
= 550 / 778
= 550
Step2:
LCM(2, 235) = 470
GCD(2, 235) = ( 2 x 235 ) / 470
= 2 / 235
= 2
Step3:
LCM(1, 805) = 805
GCD(1, 805) = ( 1 x 805 ) / 805
= 1 / 805
= 1
So, Greatest Common Divisor of 550, 778, 235, 805 is 1
