Given numbers are 968, 122, 644, 143
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(968, 122) = 59048
GCD(968, 122) = ( 968 x 122 ) / 59048
= 968 / 122
= 968
Step2:
LCM(2, 644) = 644
GCD(2, 644) = ( 2 x 644 ) / 644
= 2 / 644
= 2
Step3:
LCM(2, 143) = 286
GCD(2, 143) = ( 2 x 143 ) / 286
= 2 / 143
= 2
So, Greatest Common Divisor of 968, 122, 644, 143 is 1
