Given numbers are 839, 841, 286, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(839, 841) = 705599
GCD(839, 841) = ( 839 x 841 ) / 705599
= 839 / 841
= 839
Step2:
LCM(1, 286) = 286
GCD(1, 286) = ( 1 x 286 ) / 286
= 1 / 286
= 1
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 839, 841, 286, 644 is 1
