Given numbers are 441, 196, 143, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(441, 196) = 1764
GCD(441, 196) = ( 441 x 196 ) / 1764
= 441 / 196
= 441
Step2:
LCM(49, 143) = 7007
GCD(49, 143) = ( 49 x 143 ) / 7007
= 49 / 143
= 49
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 441, 196, 143, 921 is 1
