Given numbers are 653, 422, 672, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(653, 422) = 275566
GCD(653, 422) = ( 653 x 422 ) / 275566
= 653 / 422
= 653
Step2:
LCM(1, 672) = 672
GCD(1, 672) = ( 1 x 672 ) / 672
= 1 / 672
= 1
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 653, 422, 672, 257 is 1
