Given numbers are 426, 415, 561, 973
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(426, 415) = 176790
GCD(426, 415) = ( 426 x 415 ) / 176790
= 426 / 415
= 426
Step2:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
Step3:
LCM(1, 973) = 973
GCD(1, 973) = ( 1 x 973 ) / 973
= 1 / 973
= 1
So, Greatest Common Divisor of 426, 415, 561, 973 is 1
