Given numbers are 619, 221, 719, 381
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(619, 221) = 136799
GCD(619, 221) = ( 619 x 221 ) / 136799
= 619 / 221
= 619
Step2:
LCM(1, 719) = 719
GCD(1, 719) = ( 1 x 719 ) / 719
= 1 / 719
= 1
Step3:
LCM(1, 381) = 381
GCD(1, 381) = ( 1 x 381 ) / 381
= 1 / 381
= 1
So, Greatest Common Divisor of 619, 221, 719, 381 is 1
