Given numbers are 610, 164, 781, 431
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(610, 164) = 50020
GCD(610, 164) = ( 610 x 164 ) / 50020
= 610 / 164
= 610
Step2:
LCM(2, 781) = 1562
GCD(2, 781) = ( 2 x 781 ) / 1562
= 2 / 781
= 2
Step3:
LCM(1, 431) = 431
GCD(1, 431) = ( 1 x 431 ) / 431
= 1 / 431
= 1
So, Greatest Common Divisor of 610, 164, 781, 431 is 1
