GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(370, 178) = 32930
GCD(370, 178) = ( 370 x 178 ) / 32930
= 370 / 178
= 370
Step2:
LCM(2, 794) = 794
GCD(2, 794) = ( 2 x 794 ) / 794
= 2 / 794
= 2
Step3:
LCM(2, 438) = 438
GCD(2, 438) = ( 2 x 438 ) / 438
= 2 / 438
= 2
So, Greatest Common Divisor of 370, 178, 794, 438 is 2
