Given numbers are 280, 558, 779, 654
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 558) = 78120
GCD(280, 558) = ( 280 x 558 ) / 78120
= 280 / 558
= 280
Step2:
LCM(2, 779) = 1558
GCD(2, 779) = ( 2 x 779 ) / 1558
= 2 / 779
= 2
Step3:
LCM(1, 654) = 654
GCD(1, 654) = ( 1 x 654 ) / 654
= 1 / 654
= 1
So, Greatest Common Divisor of 280, 558, 779, 654 is 1
