GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(189, 336) = 3024
GCD(189, 336) = ( 189 x 336 ) / 3024
= 189 / 336
= 189
Step2:
LCM(21, 751) = 15771
GCD(21, 751) = ( 21 x 751 ) / 15771
= 21 / 751
= 21
Step3:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
So, Greatest Common Divisor of 189, 336, 751, 981 is 1
