Given numbers are 261, 821, 318, 426
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(261, 821) = 214281
GCD(261, 821) = ( 261 x 821 ) / 214281
= 261 / 821
= 261
Step2:
LCM(1, 318) = 318
GCD(1, 318) = ( 1 x 318 ) / 318
= 1 / 318
= 1
Step3:
LCM(1, 426) = 426
GCD(1, 426) = ( 1 x 426 ) / 426
= 1 / 426
= 1
So, Greatest Common Divisor of 261, 821, 318, 426 is 1
