Given numbers are 830, 836, 971, 987
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(830, 836) = 346940
GCD(830, 836) = ( 830 x 836 ) / 346940
= 830 / 836
= 830
Step2:
LCM(2, 971) = 1942
GCD(2, 971) = ( 2 x 971 ) / 1942
= 2 / 971
= 2
Step3:
LCM(1, 987) = 987
GCD(1, 987) = ( 1 x 987 ) / 987
= 1 / 987
= 1
So, Greatest Common Divisor of 830, 836, 971, 987 is 1
