Given numbers are 340, 485, 917, 621
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(340, 485) = 32980
GCD(340, 485) = ( 340 x 485 ) / 32980
= 340 / 485
= 340
Step2:
LCM(5, 917) = 4585
GCD(5, 917) = ( 5 x 917 ) / 4585
= 5 / 917
= 5
Step3:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
So, Greatest Common Divisor of 340, 485, 917, 621 is 1
