Given numbers are 738, 538, 891, 440
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(738, 538) = 198522
GCD(738, 538) = ( 738 x 538 ) / 198522
= 738 / 538
= 738
Step2:
LCM(2, 891) = 1782
GCD(2, 891) = ( 2 x 891 ) / 1782
= 2 / 891
= 2
Step3:
LCM(1, 440) = 440
GCD(1, 440) = ( 1 x 440 ) / 440
= 1 / 440
= 1
So, Greatest Common Divisor of 738, 538, 891, 440 is 1
