Given numbers are 411, 980, 165, 320
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(411, 980) = 402780
GCD(411, 980) = ( 411 x 980 ) / 402780
= 411 / 980
= 411
Step2:
LCM(1, 165) = 165
GCD(1, 165) = ( 1 x 165 ) / 165
= 1 / 165
= 1
Step3:
LCM(1, 320) = 320
GCD(1, 320) = ( 1 x 320 ) / 320
= 1 / 320
= 1
So, Greatest Common Divisor of 411, 980, 165, 320 is 1
