Given numbers are 355, 257, 219, 190
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(355, 257) = 91235
GCD(355, 257) = ( 355 x 257 ) / 91235
= 355 / 257
= 355
Step2:
LCM(1, 219) = 219
GCD(1, 219) = ( 1 x 219 ) / 219
= 1 / 219
= 1
Step3:
LCM(1, 190) = 190
GCD(1, 190) = ( 1 x 190 ) / 190
= 1 / 190
= 1
So, Greatest Common Divisor of 355, 257, 219, 190 is 1
