Given numbers are 208, 771, 117, 905
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(208, 771) = 160368
GCD(208, 771) = ( 208 x 771 ) / 160368
= 208 / 771
= 208
Step2:
LCM(1, 117) = 117
GCD(1, 117) = ( 1 x 117 ) / 117
= 1 / 117
= 1
Step3:
LCM(1, 905) = 905
GCD(1, 905) = ( 1 x 905 ) / 905
= 1 / 905
= 1
So, Greatest Common Divisor of 208, 771, 117, 905 is 1
