Given numbers are 275, 210, 628, 505
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(275, 210) = 11550
GCD(275, 210) = ( 275 x 210 ) / 11550
= 275 / 210
= 275
Step2:
LCM(5, 628) = 3140
GCD(5, 628) = ( 5 x 628 ) / 3140
= 5 / 628
= 5
Step3:
LCM(1, 505) = 505
GCD(1, 505) = ( 1 x 505 ) / 505
= 1 / 505
= 1
So, Greatest Common Divisor of 275, 210, 628, 505 is 1
