Given numbers are 626, 360, 163, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(626, 360) = 112680
GCD(626, 360) = ( 626 x 360 ) / 112680
= 626 / 360
= 626
Step2:
LCM(2, 163) = 326
GCD(2, 163) = ( 2 x 163 ) / 326
= 2 / 163
= 2
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 626, 360, 163, 644 is 1
