GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(491, 965) = 473815
GCD(491, 965) = ( 491 x 965 ) / 473815
= 491 / 965
= 491
Step2:
LCM(1, 945) = 945
GCD(1, 945) = ( 1 x 945 ) / 945
= 1 / 945
= 1
Step3:
LCM(1, 715) = 715
GCD(1, 715) = ( 1 x 715 ) / 715
= 1 / 715
= 1
So, Greatest Common Divisor of 491, 965, 945, 715 is 1
