Given numbers are 487, 428, 653, 259
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(487, 428) = 208436
GCD(487, 428) = ( 487 x 428 ) / 208436
= 487 / 428
= 487
Step2:
LCM(1, 653) = 653
GCD(1, 653) = ( 1 x 653 ) / 653
= 1 / 653
= 1
Step3:
LCM(1, 259) = 259
GCD(1, 259) = ( 1 x 259 ) / 259
= 1 / 259
= 1
So, Greatest Common Divisor of 487, 428, 653, 259 is 1
