GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(348, 249) = 28884
GCD(348, 249) = ( 348 x 249 ) / 28884
= 348 / 249
= 348
Step2:
LCM(3, 971) = 2913
GCD(3, 971) = ( 3 x 971 ) / 2913
= 3 / 971
= 3
Step3:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
So, Greatest Common Divisor of 348, 249, 971, 620 is 1
