Given numbers are 856, 916, 253, 813
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(856, 916) = 196024
GCD(856, 916) = ( 856 x 916 ) / 196024
= 856 / 916
= 856
Step2:
LCM(4, 253) = 1012
GCD(4, 253) = ( 4 x 253 ) / 1012
= 4 / 253
= 4
Step3:
LCM(1, 813) = 813
GCD(1, 813) = ( 1 x 813 ) / 813
= 1 / 813
= 1
So, Greatest Common Divisor of 856, 916, 253, 813 is 1
