Given numbers are 787, 860, 695, 690
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(787, 860) = 676820
GCD(787, 860) = ( 787 x 860 ) / 676820
= 787 / 860
= 787
Step2:
LCM(1, 695) = 695
GCD(1, 695) = ( 1 x 695 ) / 695
= 1 / 695
= 1
Step3:
LCM(1, 690) = 690
GCD(1, 690) = ( 1 x 690 ) / 690
= 1 / 690
= 1
So, Greatest Common Divisor of 787, 860, 695, 690 is 1
