Given numbers are 648, 971, 307, 133

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(648, 971) = 629208

GCD(648, 971) = ( 648 x 971 ) / 629208

= 648 / 971

= 648

Step2:

LCM(1, 307) = 307

GCD(1, 307) = ( 1 x 307 ) / 307

= 1 / 307

= 1

Step3:

LCM(1, 133) = 133

GCD(1, 133) = ( 1 x 133 ) / 133

= 1 / 133

= 1

So, Greatest Common Divisor of 648, 971, 307, 133 is 1
