Given numbers are 661, 961, 512, 807
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(661, 961) = 635221
GCD(661, 961) = ( 661 x 961 ) / 635221
= 661 / 961
= 661
Step2:
LCM(1, 512) = 512
GCD(1, 512) = ( 1 x 512 ) / 512
= 1 / 512
= 1
Step3:
LCM(1, 807) = 807
GCD(1, 807) = ( 1 x 807 ) / 807
= 1 / 807
= 1
So, Greatest Common Divisor of 661, 961, 512, 807 is 1
