Given numbers are 890, 931, 661, 686
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(890, 931) = 828590
GCD(890, 931) = ( 890 x 931 ) / 828590
= 890 / 931
= 890
Step2:
LCM(1, 661) = 661
GCD(1, 661) = ( 1 x 661 ) / 661
= 1 / 661
= 1
Step3:
LCM(1, 686) = 686
GCD(1, 686) = ( 1 x 686 ) / 686
= 1 / 686
= 1
So, Greatest Common Divisor of 890, 931, 661, 686 is 1
