GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(245, 945) = 6615
GCD(245, 945) = ( 245 x 945 ) / 6615
= 245 / 945
= 245
Step2:
LCM(35, 163) = 5705
GCD(35, 163) = ( 35 x 163 ) / 5705
= 35 / 163
= 35
Step3:
LCM(1, 819) = 819
GCD(1, 819) = ( 1 x 819 ) / 819
= 1 / 819
= 1
So, Greatest Common Divisor of 245, 945, 163, 819 is 1
