Given numbers are 449, 690, 562, 558
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(449, 690) = 309810
GCD(449, 690) = ( 449 x 690 ) / 309810
= 449 / 690
= 449
Step2:
LCM(1, 562) = 562
GCD(1, 562) = ( 1 x 562 ) / 562
= 1 / 562
= 1
Step3:
LCM(1, 558) = 558
GCD(1, 558) = ( 1 x 558 ) / 558
= 1 / 558
= 1
So, Greatest Common Divisor of 449, 690, 562, 558 is 1
