Given numbers are 890, 748, 491, 305
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(890, 748) = 332860
GCD(890, 748) = ( 890 x 748 ) / 332860
= 890 / 748
= 890
Step2:
LCM(2, 491) = 982
GCD(2, 491) = ( 2 x 491 ) / 982
= 2 / 491
= 2
Step3:
LCM(1, 305) = 305
GCD(1, 305) = ( 1 x 305 ) / 305
= 1 / 305
= 1
So, Greatest Common Divisor of 890, 748, 491, 305 is 1
