Given numbers are 949, 143, 957, 661
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(949, 143) = 10439
GCD(949, 143) = ( 949 x 143 ) / 10439
= 949 / 143
= 949
Step2:
LCM(13, 957) = 12441
GCD(13, 957) = ( 13 x 957 ) / 12441
= 13 / 957
= 13
Step3:
LCM(1, 661) = 661
GCD(1, 661) = ( 1 x 661 ) / 661
= 1 / 661
= 1
So, Greatest Common Divisor of 949, 143, 957, 661 is 1
