Given numbers are 860, 609, 781, 447
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(860, 609) = 523740
GCD(860, 609) = ( 860 x 609 ) / 523740
= 860 / 609
= 860
Step2:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
Step3:
LCM(1, 447) = 447
GCD(1, 447) = ( 1 x 447 ) / 447
= 1 / 447
= 1
So, Greatest Common Divisor of 860, 609, 781, 447 is 1
