Given numbers are 625, 644, 830, 164
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(625, 644) = 402500
GCD(625, 644) = ( 625 x 644 ) / 402500
= 625 / 644
= 625
Step2:
LCM(1, 830) = 830
GCD(1, 830) = ( 1 x 830 ) / 830
= 1 / 830
= 1
Step3:
LCM(1, 164) = 164
GCD(1, 164) = ( 1 x 164 ) / 164
= 1 / 164
= 1
So, Greatest Common Divisor of 625, 644, 830, 164 is 1
