Given numbers are 425, 194, 721, 668
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(425, 194) = 82450
GCD(425, 194) = ( 425 x 194 ) / 82450
= 425 / 194
= 425
Step2:
LCM(1, 721) = 721
GCD(1, 721) = ( 1 x 721 ) / 721
= 1 / 721
= 1
Step3:
LCM(1, 668) = 668
GCD(1, 668) = ( 1 x 668 ) / 668
= 1 / 668
= 1
So, Greatest Common Divisor of 425, 194, 721, 668 is 1
