Given numbers are 398, 302, 821, 574
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 302) = 60098
GCD(398, 302) = ( 398 x 302 ) / 60098
= 398 / 302
= 398
Step2:
LCM(2, 821) = 1642
GCD(2, 821) = ( 2 x 821 ) / 1642
= 2 / 821
= 2
Step3:
LCM(1, 574) = 574
GCD(1, 574) = ( 1 x 574 ) / 574
= 1 / 574
= 1
So, Greatest Common Divisor of 398, 302, 821, 574 is 1
