GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 488) = 52216
GCD(428, 488) = ( 428 x 488 ) / 52216
= 428 / 488
= 428
Step2:
LCM(4, 561) = 2244
GCD(4, 561) = ( 4 x 561 ) / 2244
= 4 / 561
= 4
Step3:
LCM(1, 454) = 454
GCD(1, 454) = ( 1 x 454 ) / 454
= 1 / 454
= 1
So, Greatest Common Divisor of 428, 488, 561, 454 is 1
