GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(787, 619) = 487153
GCD(787, 619) = ( 787 x 619 ) / 487153
= 787 / 619
= 787
Step2:
LCM(1, 276) = 276
GCD(1, 276) = ( 1 x 276 ) / 276
= 1 / 276
= 1
Step3:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
So, Greatest Common Divisor of 787, 619, 276, 978 is 1
