Given numbers are 821, 425, 907, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(821, 425) = 348925
GCD(821, 425) = ( 821 x 425 ) / 348925
= 821 / 425
= 821
Step2:
LCM(1, 907) = 907
GCD(1, 907) = ( 1 x 907 ) / 907
= 1 / 907
= 1
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 821, 425, 907, 921 is 1
