Given numbers are 210, 228, 726, 821
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(210, 228) = 7980
GCD(210, 228) = ( 210 x 228 ) / 7980
= 210 / 228
= 210
Step2:
LCM(6, 726) = 726
GCD(6, 726) = ( 6 x 726 ) / 726
= 6 / 726
= 6
Step3:
LCM(6, 821) = 4926
GCD(6, 821) = ( 6 x 821 ) / 4926
= 6 / 821
= 6
So, Greatest Common Divisor of 210, 228, 726, 821 is 1
