Given numbers are 408, 769, 202, 398
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(408, 769) = 313752
GCD(408, 769) = ( 408 x 769 ) / 313752
= 408 / 769
= 408
Step2:
LCM(1, 202) = 202
GCD(1, 202) = ( 1 x 202 ) / 202
= 1 / 202
= 1
Step3:
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
= 1 / 398
= 1
So, Greatest Common Divisor of 408, 769, 202, 398 is 1
