Given numbers are 690, 236, 719, 891

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(690, 236) = 81420

GCD(690, 236) = ( 690 x 236 ) / 81420

= 690 / 236

= 690

Step2:

LCM(2, 719) = 1438

GCD(2, 719) = ( 2 x 719 ) / 1438

= 2 / 719

= 2

Step3:

LCM(1, 891) = 891

GCD(1, 891) = ( 1 x 891 ) / 891

= 1 / 891

= 1

So, Greatest Common Divisor of 690, 236, 719, 891 is 1
