Given numbers are 397, 417, 552, 812
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(397, 417) = 165549
GCD(397, 417) = ( 397 x 417 ) / 165549
= 397 / 417
= 397
Step2:
LCM(1, 552) = 552
GCD(1, 552) = ( 1 x 552 ) / 552
= 1 / 552
= 1
Step3:
LCM(1, 812) = 812
GCD(1, 812) = ( 1 x 812 ) / 812
= 1 / 812
= 1
So, Greatest Common Divisor of 397, 417, 552, 812 is 1
