Given numbers are 778, 220, 519, 206
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(778, 220) = 85580
GCD(778, 220) = ( 778 x 220 ) / 85580
= 778 / 220
= 778
Step2:
LCM(2, 519) = 1038
GCD(2, 519) = ( 2 x 519 ) / 1038
= 2 / 519
= 2
Step3:
LCM(1, 206) = 206
GCD(1, 206) = ( 1 x 206 ) / 206
= 1 / 206
= 1
So, Greatest Common Divisor of 778, 220, 519, 206 is 1
