Given numbers are 838, 164, 679, 817
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(838, 164) = 68716
GCD(838, 164) = ( 838 x 164 ) / 68716
= 838 / 164
= 838
Step2:
LCM(2, 679) = 1358
GCD(2, 679) = ( 2 x 679 ) / 1358
= 2 / 679
= 2
Step3:
LCM(1, 817) = 817
GCD(1, 817) = ( 1 x 817 ) / 817
= 1 / 817
= 1
So, Greatest Common Divisor of 838, 164, 679, 817 is 1
