Given numbers are 667, 270, 557, 438
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(667, 270) = 180090
GCD(667, 270) = ( 667 x 270 ) / 180090
= 667 / 270
= 667
Step2:
LCM(1, 557) = 557
GCD(1, 557) = ( 1 x 557 ) / 557
= 1 / 557
= 1
Step3:
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
= 1 / 438
= 1
So, Greatest Common Divisor of 667, 270, 557, 438 is 1
