Given numbers are 828, 787, 391, 293
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(828, 787) = 651636
GCD(828, 787) = ( 828 x 787 ) / 651636
= 828 / 787
= 828
Step2:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
Step3:
LCM(1, 293) = 293
GCD(1, 293) = ( 1 x 293 ) / 293
= 1 / 293
= 1
So, Greatest Common Divisor of 828, 787, 391, 293 is 1
