Given numbers are 820, 694, 439, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 694) = 284540
GCD(820, 694) = ( 820 x 694 ) / 284540
= 820 / 694
= 820
Step2:
LCM(2, 439) = 878
GCD(2, 439) = ( 2 x 439 ) / 878
= 2 / 439
= 2
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 820, 694, 439, 781 is 1
