Given numbers are 438, 358, 592, 685
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 358) = 78402
GCD(438, 358) = ( 438 x 358 ) / 78402
= 438 / 358
= 438
Step2:
LCM(2, 592) = 592
GCD(2, 592) = ( 2 x 592 ) / 592
= 2 / 592
= 2
Step3:
LCM(2, 685) = 1370
GCD(2, 685) = ( 2 x 685 ) / 1370
= 2 / 685
= 2
So, Greatest Common Divisor of 438, 358, 592, 685 is 1
