Given numbers are 425, 706, 684, 991
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(425, 706) = 300050
GCD(425, 706) = ( 425 x 706 ) / 300050
= 425 / 706
= 425
Step2:
LCM(1, 684) = 684
GCD(1, 684) = ( 1 x 684 ) / 684
= 1 / 684
= 1
Step3:
LCM(1, 991) = 991
GCD(1, 991) = ( 1 x 991 ) / 991
= 1 / 991
= 1
So, Greatest Common Divisor of 425, 706, 684, 991 is 1
