Given numbers are 648, 687, 635, 194
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 687) = 148392
GCD(648, 687) = ( 648 x 687 ) / 148392
= 648 / 687
= 648
Step2:
LCM(3, 635) = 1905
GCD(3, 635) = ( 3 x 635 ) / 1905
= 3 / 635
= 3
Step3:
LCM(1, 194) = 194
GCD(1, 194) = ( 1 x 194 ) / 194
= 1 / 194
= 1
So, Greatest Common Divisor of 648, 687, 635, 194 is 1
