Given numbers are 419, 245, 562, 249
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(419, 245) = 102655
GCD(419, 245) = ( 419 x 245 ) / 102655
= 419 / 245
= 419
Step2:
LCM(1, 562) = 562
GCD(1, 562) = ( 1 x 562 ) / 562
= 1 / 562
= 1
Step3:
LCM(1, 249) = 249
GCD(1, 249) = ( 1 x 249 ) / 249
= 1 / 249
= 1
So, Greatest Common Divisor of 419, 245, 562, 249 is 1
