Given numbers are 170, 362, 449, 290
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(170, 362) = 30770
GCD(170, 362) = ( 170 x 362 ) / 30770
= 170 / 362
= 170
Step2:
LCM(2, 449) = 898
GCD(2, 449) = ( 2 x 449 ) / 898
= 2 / 449
= 2
Step3:
LCM(1, 290) = 290
GCD(1, 290) = ( 1 x 290 ) / 290
= 1 / 290
= 1
So, Greatest Common Divisor of 170, 362, 449, 290 is 1
