GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(164, 346) = 28372
GCD(164, 346) = ( 164 x 346 ) / 28372
= 164 / 346
= 164
Step2:
LCM(2, 768) = 768
GCD(2, 768) = ( 2 x 768 ) / 768
= 2 / 768
= 2
Step3:
LCM(2, 639) = 1278
GCD(2, 639) = ( 2 x 639 ) / 1278
= 2 / 639
= 2
So, Greatest Common Divisor of 164, 346, 768, 639 is 1
