Given numbers are 805, 119, 661, 143
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(805, 119) = 13685
GCD(805, 119) = ( 805 x 119 ) / 13685
= 805 / 119
= 805
Step2:
LCM(7, 661) = 4627
GCD(7, 661) = ( 7 x 661 ) / 4627
= 7 / 661
= 7
Step3:
LCM(1, 143) = 143
GCD(1, 143) = ( 1 x 143 ) / 143
= 1 / 143
= 1
So, Greatest Common Divisor of 805, 119, 661, 143 is 1
