Given numbers are 635, 140, 719, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(635, 140) = 17780
GCD(635, 140) = ( 635 x 140 ) / 17780
= 635 / 140
= 635
Step2:
LCM(5, 719) = 3595
GCD(5, 719) = ( 5 x 719 ) / 3595
= 5 / 719
= 5
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 635, 140, 719, 644 is 1
