GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 598) = 8372
GCD(644, 598) = ( 644 x 598 ) / 8372
= 644 / 598
= 644
Step2:
LCM(46, 253) = 506
GCD(46, 253) = ( 46 x 253 ) / 506
= 46 / 253
= 46
Step3:
LCM(23, 916) = 21068
GCD(23, 916) = ( 23 x 916 ) / 21068
= 23 / 916
= 23
So, Greatest Common Divisor of 644, 598, 253, 916 is 1
