Given numbers are 665, 644, 722, 166
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(665, 644) = 61180
GCD(665, 644) = ( 665 x 644 ) / 61180
= 665 / 644
= 665
Step2:
LCM(7, 722) = 5054
GCD(7, 722) = ( 7 x 722 ) / 5054
= 7 / 722
= 7
Step3:
LCM(1, 166) = 166
GCD(1, 166) = ( 1 x 166 ) / 166
= 1 / 166
= 1
So, Greatest Common Divisor of 665, 644, 722, 166 is 1
