Given numbers are 293, 891, 356, 821
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(293, 891) = 261063
GCD(293, 891) = ( 293 x 891 ) / 261063
= 293 / 891
= 293
Step2:
LCM(1, 356) = 356
GCD(1, 356) = ( 1 x 356 ) / 356
= 1 / 356
= 1
Step3:
LCM(1, 821) = 821
GCD(1, 821) = ( 1 x 821 ) / 821
= 1 / 821
= 1
So, Greatest Common Divisor of 293, 891, 356, 821 is 1
