Given numbers are 690, 988, 65, 911

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

Apply this formula for all numbers.

Step1:

LCM(690, 988) = 340860

GCD(690, 988) = ( 690 x 988 ) / 340860

= 690 / 988

= 690

Step2:

LCM(2, 65) = 130

GCD(2, 65) = ( 2 x 65 ) / 130

= 2 / 65

= 2

Step3:

LCM(1, 911) = 911

GCD(1, 911) = ( 1 x 911 ) / 911

= 1 / 911

= 1

So, Greatest Common Divisor of 690, 988, 65, 911 is 1
