Given numbers are 874, 646, 505, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(874, 646) = 14858
GCD(874, 646) = ( 874 x 646 ) / 14858
= 874 / 646
= 874
Step2:
LCM(38, 505) = 19190
GCD(38, 505) = ( 38 x 505 ) / 19190
= 38 / 505
= 38
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 874, 646, 505, 649 is 1
