Given numbers are 193, 556, 780, 612
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(193, 556) = 107308
GCD(193, 556) = ( 193 x 556 ) / 107308
= 193 / 556
= 193
Step2:
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
= 1 / 780
= 1
Step3:
LCM(1, 612) = 612
GCD(1, 612) = ( 1 x 612 ) / 612
= 1 / 612
= 1
So, Greatest Common Divisor of 193, 556, 780, 612 is 1
