Given numbers are 728, 378, 383, 869
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(728, 378) = 19656
GCD(728, 378) = ( 728 x 378 ) / 19656
= 728 / 378
= 728
Step2:
LCM(14, 383) = 5362
GCD(14, 383) = ( 14 x 383 ) / 5362
= 14 / 383
= 14
Step3:
LCM(1, 869) = 869
GCD(1, 869) = ( 1 x 869 ) / 869
= 1 / 869
= 1
So, Greatest Common Divisor of 728, 378, 383, 869 is 1
