GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(378, 981) = 41202
GCD(378, 981) = ( 378 x 981 ) / 41202
= 378 / 981
= 378
Step2:
LCM(9, 868) = 7812
GCD(9, 868) = ( 9 x 868 ) / 7812
= 9 / 868
= 9
Step3:
LCM(1, 735) = 735
GCD(1, 735) = ( 1 x 735 ) / 735
= 1 / 735
= 1
So, Greatest Common Divisor of 378, 981, 868, 735 is 1
