GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 228) = 37164
GCD(978, 228) = ( 978 x 228 ) / 37164
= 978 / 228
= 978
Step2:
LCM(6, 382) = 1146
GCD(6, 382) = ( 6 x 382 ) / 1146
= 6 / 382
= 6
Step3:
LCM(2, 785) = 1570
GCD(2, 785) = ( 2 x 785 ) / 1570
= 2 / 785
= 2
So, Greatest Common Divisor of 978, 228, 382, 785 is 1
