Given numbers are 260, 695, 21, 124
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(260, 695) = 36140
GCD(260, 695) = ( 260 x 695 ) / 36140
= 260 / 695
= 260
Step2:
LCM(5, 21) = 105
GCD(5, 21) = ( 5 x 21 ) / 105
= 5 / 21
= 5
Step3:
LCM(1, 124) = 124
GCD(1, 124) = ( 1 x 124 ) / 124
= 1 / 124
= 1
So, Greatest Common Divisor of 260, 695, 21, 124 is 1
