Given numbers are 687, 602, 628, 215
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 602) = 413574
GCD(687, 602) = ( 687 x 602 ) / 413574
= 687 / 602
= 687
Step2:
LCM(1, 628) = 628
GCD(1, 628) = ( 1 x 628 ) / 628
= 1 / 628
= 1
Step3:
LCM(1, 215) = 215
GCD(1, 215) = ( 1 x 215 ) / 215
= 1 / 215
= 1
So, Greatest Common Divisor of 687, 602, 628, 215 is 1
