Given numbers are 679, 621, 641, 791
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(679, 621) = 421659
GCD(679, 621) = ( 679 x 621 ) / 421659
= 679 / 621
= 679
Step2:
LCM(1, 641) = 641
GCD(1, 641) = ( 1 x 641 ) / 641
= 1 / 641
= 1
Step3:
LCM(1, 791) = 791
GCD(1, 791) = ( 1 x 791 ) / 791
= 1 / 791
= 1
So, Greatest Common Divisor of 679, 621, 641, 791 is 1
