Given numbers are 371, 280, 185, 657
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(371, 280) = 14840
GCD(371, 280) = ( 371 x 280 ) / 14840
= 371 / 280
= 371
Step2:
LCM(7, 185) = 1295
GCD(7, 185) = ( 7 x 185 ) / 1295
= 7 / 185
= 7
Step3:
LCM(1, 657) = 657
GCD(1, 657) = ( 1 x 657 ) / 657
= 1 / 657
= 1
So, Greatest Common Divisor of 371, 280, 185, 657 is 1
