Given numbers are 690, 214, 419, 401

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

Apply this formula for all numbers.

Step1:

LCM(690, 214) = 73830

GCD(690, 214) = ( 690 x 214 ) / 73830

= 690 / 214

= 690

Step2:

LCM(2, 419) = 838

GCD(2, 419) = ( 2 x 419 ) / 838

= 2 / 419

= 2

Step3:

LCM(1, 401) = 401

GCD(1, 401) = ( 1 x 401 ) / 401

= 1 / 401

= 1

So, Greatest Common Divisor of 690, 214, 419, 401 is 1
