GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(558, 972) = 30132
GCD(558, 972) = ( 558 x 972 ) / 30132
= 558 / 972
= 558
Step2:
LCM(18, 219) = 1314
GCD(18, 219) = ( 18 x 219 ) / 1314
= 18 / 219
= 18
Step3:
LCM(3, 248) = 744
GCD(3, 248) = ( 3 x 248 ) / 744
= 3 / 248
= 3
So, Greatest Common Divisor of 558, 972, 219, 248 is 1
