Given numbers are 990, 595, 549, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(990, 595) = 117810
GCD(990, 595) = ( 990 x 595 ) / 117810
= 990 / 595
= 990
Step2:
LCM(5, 549) = 2745
GCD(5, 549) = ( 5 x 549 ) / 2745
= 5 / 549
= 5
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 990, 595, 549, 257 is 1
