Given numbers are 921, 144, 211, 100
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(921, 144) = 44208
GCD(921, 144) = ( 921 x 144 ) / 44208
= 921 / 144
= 921
Step2:
LCM(3, 211) = 633
GCD(3, 211) = ( 3 x 211 ) / 633
= 3 / 211
= 3
Step3:
LCM(1, 100) = 100
GCD(1, 100) = ( 1 x 100 ) / 100
= 1 / 100
= 1
So, Greatest Common Divisor of 921, 144, 211, 100 is 1
