Given numbers are 964, 821, 620, 231
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(964, 821) = 791444
GCD(964, 821) = ( 964 x 821 ) / 791444
= 964 / 821
= 964
Step2:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
Step3:
LCM(1, 231) = 231
GCD(1, 231) = ( 1 x 231 ) / 231
= 1 / 231
= 1
So, Greatest Common Divisor of 964, 821, 620, 231 is 1
