Given numbers are 738, 805, 420, 685
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(738, 805) = 594090
GCD(738, 805) = ( 738 x 805 ) / 594090
= 738 / 805
= 738
Step2:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
Step3:
LCM(1, 685) = 685
GCD(1, 685) = ( 1 x 685 ) / 685
= 1 / 685
= 1
So, Greatest Common Divisor of 738, 805, 420, 685 is 1
