Given numbers are 225, 670, 680, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(225, 670) = 30150
GCD(225, 670) = ( 225 x 670 ) / 30150
= 225 / 670
= 225
Step2:
LCM(5, 680) = 680
GCD(5, 680) = ( 5 x 680 ) / 680
= 5 / 680
= 5
Step3:
LCM(5, 221) = 1105
GCD(5, 221) = ( 5 x 221 ) / 1105
= 5 / 221
= 5
So, Greatest Common Divisor of 225, 670, 680, 221 is 1
