Given numbers are 856, 870, 804, 679
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(856, 870) = 372360
GCD(856, 870) = ( 856 x 870 ) / 372360
= 856 / 870
= 856
Step2:
LCM(2, 804) = 804
GCD(2, 804) = ( 2 x 804 ) / 804
= 2 / 804
= 2
Step3:
LCM(2, 679) = 1358
GCD(2, 679) = ( 2 x 679 ) / 1358
= 2 / 679
= 2
So, Greatest Common Divisor of 856, 870, 804, 679 is 1
