Given numbers are 781, 412, 405, 695
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(781, 412) = 321772
GCD(781, 412) = ( 781 x 412 ) / 321772
= 781 / 412
= 781
Step2:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
Step3:
LCM(1, 695) = 695
GCD(1, 695) = ( 1 x 695 ) / 695
= 1 / 695
= 1
So, Greatest Common Divisor of 781, 412, 405, 695 is 1
