Given numbers are 785, 548, 662, 421
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(785, 548) = 430180
GCD(785, 548) = ( 785 x 548 ) / 430180
= 785 / 548
= 785
Step2:
LCM(1, 662) = 662
GCD(1, 662) = ( 1 x 662 ) / 662
= 1 / 662
= 1
Step3:
LCM(1, 421) = 421
GCD(1, 421) = ( 1 x 421 ) / 421
= 1 / 421
= 1
So, Greatest Common Divisor of 785, 548, 662, 421 is 1
