Given numbers are 89, 21, 65, 83
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(89, 21) = 1869
GCD(89, 21) = ( 89 x 21 ) / 1869
= 89 / 21
= 89
Step2:
LCM(1, 65) = 65
GCD(1, 65) = ( 1 x 65 ) / 65
= 1 / 65
= 1
Step3:
LCM(1, 83) = 83
GCD(1, 83) = ( 1 x 83 ) / 83
= 1 / 83
= 1
So, Greatest Common Divisor of 89, 21, 65, 83 is 1
