Given numbers are 430, 380, 221, 218
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(430, 380) = 16340
GCD(430, 380) = ( 430 x 380 ) / 16340
= 430 / 380
= 430
Step2:
LCM(10, 221) = 2210
GCD(10, 221) = ( 10 x 221 ) / 2210
= 10 / 221
= 10
Step3:
LCM(1, 218) = 218
GCD(1, 218) = ( 1 x 218 ) / 218
= 1 / 218
= 1
So, Greatest Common Divisor of 430, 380, 221, 218 is 1
