Given numbers are 354, 206, 87, 261
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(354, 206) = 36462
GCD(354, 206) = ( 354 x 206 ) / 36462
= 354 / 206
= 354
Step2:
LCM(2, 87) = 174
GCD(2, 87) = ( 2 x 87 ) / 174
= 2 / 87
= 2
Step3:
LCM(1, 261) = 261
GCD(1, 261) = ( 1 x 261 ) / 261
= 1 / 261
= 1
So, Greatest Common Divisor of 354, 206, 87, 261 is 1
