Given numbers are 430, 978, 511, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(430, 978) = 210270
GCD(430, 978) = ( 430 x 978 ) / 210270
= 430 / 978
= 430
Step2:
LCM(2, 511) = 1022
GCD(2, 511) = ( 2 x 511 ) / 1022
= 2 / 511
= 2
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 430, 978, 511, 781 is 1
