GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(242, 440) = 4840
GCD(242, 440) = ( 242 x 440 ) / 4840
= 242 / 440
= 242
Step2:
LCM(22, 286) = 286
GCD(22, 286) = ( 22 x 286 ) / 286
= 22 / 286
= 22
Step3:
LCM(22, 974) = 10714
GCD(22, 974) = ( 22 x 974 ) / 10714
= 22 / 974
= 22
So, Greatest Common Divisor of 242, 440, 286, 974 is 2
