GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(245, 427) = 14945
GCD(245, 427) = ( 245 x 427 ) / 14945
= 245 / 427
= 245
Step2:
LCM(7, 578) = 4046
GCD(7, 578) = ( 7 x 578 ) / 4046
= 7 / 578
= 7
Step3:
LCM(1, 743) = 743
GCD(1, 743) = ( 1 x 743 ) / 743
= 1 / 743
= 1
So, Greatest Common Divisor of 245, 427, 578, 743 is 1
