GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(749, 679) = 72653
GCD(749, 679) = ( 749 x 679 ) / 72653
= 749 / 679
= 749
Step2:
LCM(7, 813) = 5691
GCD(7, 813) = ( 7 x 813 ) / 5691
= 7 / 813
= 7
Step3:
LCM(1, 243) = 243
GCD(1, 243) = ( 1 x 243 ) / 243
= 1 / 243
= 1
So, Greatest Common Divisor of 749, 679, 813, 243 is 1
