Given numbers are 438, 849, 661, 764

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

Apply this formula for all numbers.

Step1:

LCM(438, 849) = 123954

GCD(438, 849) = ( 438 x 849 ) / 123954

= 438 / 849

= 438

Step2:

LCM(3, 661) = 1983

GCD(3, 661) = ( 3 x 661 ) / 1983

= 3 / 661

= 3

Step3:

LCM(1, 764) = 764

GCD(1, 764) = ( 1 x 764 ) / 764

= 1 / 764

= 1

So, Greatest Common Divisor of 438, 849, 661, 764 is 1
