Given numbers are 890, 904, 671, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(890, 904) = 402280
GCD(890, 904) = ( 890 x 904 ) / 402280
= 890 / 904
= 890
Step2:
LCM(2, 671) = 1342
GCD(2, 671) = ( 2 x 671 ) / 1342
= 2 / 671
= 2
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 890, 904, 671, 644 is 1
