Given numbers are 727, 775, 642, 211
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(727, 775) = 563425
GCD(727, 775) = ( 727 x 775 ) / 563425
= 727 / 775
= 727
Step2:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
Step3:
LCM(1, 211) = 211
GCD(1, 211) = ( 1 x 211 ) / 211
= 1 / 211
= 1
So, Greatest Common Divisor of 727, 775, 642, 211 is 1
