GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(908, 390) = 177060
GCD(908, 390) = ( 908 x 390 ) / 177060
= 908 / 390
= 908
Step2:
LCM(2, 782) = 782
GCD(2, 782) = ( 2 x 782 ) / 782
= 2 / 782
= 2
Step3:
LCM(2, 218) = 218
GCD(2, 218) = ( 2 x 218 ) / 218
= 2 / 218
= 2
So, Greatest Common Divisor of 908, 390, 782, 218 is 2
