Given numbers are 665, 671, 619, 575
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(665, 671) = 446215
GCD(665, 671) = ( 665 x 671 ) / 446215
= 665 / 671
= 665
Step2:
LCM(1, 619) = 619
GCD(1, 619) = ( 1 x 619 ) / 619
= 1 / 619
= 1
Step3:
LCM(1, 575) = 575
GCD(1, 575) = ( 1 x 575 ) / 575
= 1 / 575
= 1
So, Greatest Common Divisor of 665, 671, 619, 575 is 1
