Given numbers are 438, 617, 717, 185
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 617) = 270246
GCD(438, 617) = ( 438 x 617 ) / 270246
= 438 / 617
= 438
Step2:
LCM(1, 717) = 717
GCD(1, 717) = ( 1 x 717 ) / 717
= 1 / 717
= 1
Step3:
LCM(1, 185) = 185
GCD(1, 185) = ( 1 x 185 ) / 185
= 1 / 185
= 1
So, Greatest Common Divisor of 438, 617, 717, 185 is 1
