Given numbers are 342, 745, 780, 973
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(342, 745) = 254790
GCD(342, 745) = ( 342 x 745 ) / 254790
= 342 / 745
= 342
Step2:
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
= 1 / 780
= 1
Step3:
LCM(1, 973) = 973
GCD(1, 973) = ( 1 x 973 ) / 973
= 1 / 973
= 1
So, Greatest Common Divisor of 342, 745, 780, 973 is 1
