Given numbers are 143, 921, 128, 241
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(143, 921) = 131703
GCD(143, 921) = ( 143 x 921 ) / 131703
= 143 / 921
= 143
Step2:
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
= 1 / 128
= 1
Step3:
LCM(1, 241) = 241
GCD(1, 241) = ( 1 x 241 ) / 241
= 1 / 241
= 1
So, Greatest Common Divisor of 143, 921, 128, 241 is 1
