Given numbers are 257, 747, 670, 734
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(257, 747) = 191979
GCD(257, 747) = ( 257 x 747 ) / 191979
= 257 / 747
= 257
Step2:
LCM(1, 670) = 670
GCD(1, 670) = ( 1 x 670 ) / 670
= 1 / 670
= 1
Step3:
LCM(1, 734) = 734
GCD(1, 734) = ( 1 x 734 ) / 734
= 1 / 734
= 1
So, Greatest Common Divisor of 257, 747, 670, 734 is 1
