Given numbers are 821, 261, 244, 907
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(821, 261) = 214281
GCD(821, 261) = ( 821 x 261 ) / 214281
= 821 / 261
= 821
Step2:
LCM(1, 244) = 244
GCD(1, 244) = ( 1 x 244 ) / 244
= 1 / 244
= 1
Step3:
LCM(1, 907) = 907
GCD(1, 907) = ( 1 x 907 ) / 907
= 1 / 907
= 1
So, Greatest Common Divisor of 821, 261, 244, 907 is 1
