Given numbers are 267, 647, 257, 653
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(267, 647) = 172749
GCD(267, 647) = ( 267 x 647 ) / 172749
= 267 / 647
= 267
Step2:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
Step3:
LCM(1, 653) = 653
GCD(1, 653) = ( 1 x 653 ) / 653
= 1 / 653
= 1
So, Greatest Common Divisor of 267, 647, 257, 653 is 1
