Given numbers are 361, 815, 953, 553
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(361, 815) = 294215
GCD(361, 815) = ( 361 x 815 ) / 294215
= 361 / 815
= 361
Step2:
LCM(1, 953) = 953
GCD(1, 953) = ( 1 x 953 ) / 953
= 1 / 953
= 1
Step3:
LCM(1, 553) = 553
GCD(1, 553) = ( 1 x 553 ) / 553
= 1 / 553
= 1
So, Greatest Common Divisor of 361, 815, 953, 553 is 1
