Given numbers are 140, 345, 791, 657
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(140, 345) = 9660
GCD(140, 345) = ( 140 x 345 ) / 9660
= 140 / 345
= 140
Step2:
LCM(5, 791) = 3955
GCD(5, 791) = ( 5 x 791 ) / 3955
= 5 / 791
= 5
Step3:
LCM(1, 657) = 657
GCD(1, 657) = ( 1 x 657 ) / 657
= 1 / 657
= 1
So, Greatest Common Divisor of 140, 345, 791, 657 is 1
