Given numbers are 847, 422, 420, 713
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(847, 422) = 357434
GCD(847, 422) = ( 847 x 422 ) / 357434
= 847 / 422
= 847
Step2:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
Step3:
LCM(1, 713) = 713
GCD(1, 713) = ( 1 x 713 ) / 713
= 1 / 713
= 1
So, Greatest Common Divisor of 847, 422, 420, 713 is 1
