Given numbers are 59, 91, 57, 21
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(59, 91) = 5369
GCD(59, 91) = ( 59 x 91 ) / 5369
= 59 / 91
= 59
Step2:
LCM(1, 57) = 57
GCD(1, 57) = ( 1 x 57 ) / 57
= 1 / 57
= 1
Step3:
LCM(1, 21) = 21
GCD(1, 21) = ( 1 x 21 ) / 21
= 1 / 21
= 1
So, Greatest Common Divisor of 59, 91, 57, 21 is 1
