Given numbers are 454, 438, 437, 280
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(454, 438) = 99426
GCD(454, 438) = ( 454 x 438 ) / 99426
= 454 / 438
= 454
Step2:
LCM(2, 437) = 874
GCD(2, 437) = ( 2 x 437 ) / 874
= 2 / 437
= 2
Step3:
LCM(1, 280) = 280
GCD(1, 280) = ( 1 x 280 ) / 280
= 1 / 280
= 1
So, Greatest Common Divisor of 454, 438, 437, 280 is 1
