Given numbers are 487, 780, 565, 485
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(487, 780) = 379860
GCD(487, 780) = ( 487 x 780 ) / 379860
= 487 / 780
= 487
Step2:
LCM(1, 565) = 565
GCD(1, 565) = ( 1 x 565 ) / 565
= 1 / 565
= 1
Step3:
LCM(1, 485) = 485
GCD(1, 485) = ( 1 x 485 ) / 485
= 1 / 485
= 1
So, Greatest Common Divisor of 487, 780, 565, 485 is 1
