Given numbers are 763, 405, 851, 987
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(763, 405) = 309015
GCD(763, 405) = ( 763 x 405 ) / 309015
= 763 / 405
= 763
Step2:
LCM(1, 851) = 851
GCD(1, 851) = ( 1 x 851 ) / 851
= 1 / 851
= 1
Step3:
LCM(1, 987) = 987
GCD(1, 987) = ( 1 x 987 ) / 987
= 1 / 987
= 1
So, Greatest Common Divisor of 763, 405, 851, 987 is 1
