GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(207, 945) = 21735
GCD(207, 945) = ( 207 x 945 ) / 21735
= 207 / 945
= 207
Step2:
LCM(9, 296) = 2664
GCD(9, 296) = ( 9 x 296 ) / 2664
= 9 / 296
= 9
Step3:
LCM(1, 661) = 661
GCD(1, 661) = ( 1 x 661 ) / 661
= 1 / 661
= 1
So, Greatest Common Divisor of 207, 945, 296, 661 is 1
