Given numbers are 821, 847, 407, 826
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(821, 847) = 695387
GCD(821, 847) = ( 821 x 847 ) / 695387
= 821 / 847
= 821
Step2:
LCM(1, 407) = 407
GCD(1, 407) = ( 1 x 407 ) / 407
= 1 / 407
= 1
Step3:
LCM(1, 826) = 826
GCD(1, 826) = ( 1 x 826 ) / 826
= 1 / 826
= 1
So, Greatest Common Divisor of 821, 847, 407, 826 is 1
