GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(218, 224) = 24416
GCD(218, 224) = ( 218 x 224 ) / 24416
= 218 / 224
= 218
Step2:
LCM(2, 975) = 1950
GCD(2, 975) = ( 2 x 975 ) / 1950
= 2 / 975
= 2
Step3:
LCM(1, 861) = 861
GCD(1, 861) = ( 1 x 861 ) / 861
= 1 / 861
= 1
So, Greatest Common Divisor of 218, 224, 975, 861 is 1
