Given numbers are 505, 109, 489, 370
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(505, 109) = 55045
GCD(505, 109) = ( 505 x 109 ) / 55045
= 505 / 109
= 505
Step2:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
Step3:
LCM(1, 370) = 370
GCD(1, 370) = ( 1 x 370 ) / 370
= 1 / 370
= 1
So, Greatest Common Divisor of 505, 109, 489, 370 is 1
