Given numbers are 531, 649, 886, 805
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(531, 649) = 5841
GCD(531, 649) = ( 531 x 649 ) / 5841
= 531 / 649
= 531
Step2:
LCM(59, 886) = 52274
GCD(59, 886) = ( 59 x 886 ) / 52274
= 59 / 886
= 59
Step3:
LCM(1, 805) = 805
GCD(1, 805) = ( 1 x 805 ) / 805
= 1 / 805
= 1
So, Greatest Common Divisor of 531, 649, 886, 805 is 1
