Given numbers are 780, 746, 121, 722
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 746) = 290940
GCD(780, 746) = ( 780 x 746 ) / 290940
= 780 / 746
= 780
Step2:
LCM(2, 121) = 242
GCD(2, 121) = ( 2 x 121 ) / 242
= 2 / 121
= 2
Step3:
LCM(1, 722) = 722
GCD(1, 722) = ( 1 x 722 ) / 722
= 1 / 722
= 1
So, Greatest Common Divisor of 780, 746, 121, 722 is 1
