Given numbers are 781, 223, 626, 162
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(781, 223) = 174163
GCD(781, 223) = ( 781 x 223 ) / 174163
= 781 / 223
= 781
Step2:
LCM(1, 626) = 626
GCD(1, 626) = ( 1 x 626 ) / 626
= 1 / 626
= 1
Step3:
LCM(1, 162) = 162
GCD(1, 162) = ( 1 x 162 ) / 162
= 1 / 162
= 1
So, Greatest Common Divisor of 781, 223, 626, 162 is 1
