Given numbers are 620, 285, 419, 217
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 285) = 35340
GCD(620, 285) = ( 620 x 285 ) / 35340
= 620 / 285
= 620
Step2:
LCM(5, 419) = 2095
GCD(5, 419) = ( 5 x 419 ) / 2095
= 5 / 419
= 5
Step3:
LCM(1, 217) = 217
GCD(1, 217) = ( 1 x 217 ) / 217
= 1 / 217
= 1
So, Greatest Common Divisor of 620, 285, 419, 217 is 1
