Given numbers are 456, 986, 497, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(456, 986) = 224808
GCD(456, 986) = ( 456 x 986 ) / 224808
= 456 / 986
= 456
Step2:
LCM(2, 497) = 994
GCD(2, 497) = ( 2 x 497 ) / 994
= 2 / 497
= 2
Step3:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
So, Greatest Common Divisor of 456, 986, 497, 221 is 1
