GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 904) = 621048
GCD(687, 904) = ( 687 x 904 ) / 621048
= 687 / 904
= 687
Step2:
LCM(1, 890) = 890
GCD(1, 890) = ( 1 x 890 ) / 890
= 1 / 890
= 1
Step3:
LCM(1, 192) = 192
GCD(1, 192) = ( 1 x 192 ) / 192
= 1 / 192
= 1
So, Greatest Common Divisor of 687, 904, 890, 192 is 1
