Given numbers are 398, 452, 764, 219
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 452) = 89948
GCD(398, 452) = ( 398 x 452 ) / 89948
= 398 / 452
= 398
Step2:
LCM(2, 764) = 764
GCD(2, 764) = ( 2 x 764 ) / 764
= 2 / 764
= 2
Step3:
LCM(2, 219) = 438
GCD(2, 219) = ( 2 x 219 ) / 438
= 2 / 219
= 2
So, Greatest Common Divisor of 398, 452, 764, 219 is 1
