Given numbers are 438, 311, 265, 611
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 311) = 136218
GCD(438, 311) = ( 438 x 311 ) / 136218
= 438 / 311
= 438
Step2:
LCM(1, 265) = 265
GCD(1, 265) = ( 1 x 265 ) / 265
= 1 / 265
= 1
Step3:
LCM(1, 611) = 611
GCD(1, 611) = ( 1 x 611 ) / 611
= 1 / 611
= 1
So, Greatest Common Divisor of 438, 311, 265, 611 is 1
