Prime factors of 561 are 3 x 11 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 662, 661, 402, 561
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(662, 661) = 437582
GCD(662, 661) = ( 662 x 661 ) / 437582
= 662 / 661
= 662
Step2:
LCM(1, 402) = 402
GCD(1, 402) = ( 1 x 402 ) / 402
= 1 / 402
= 1
Step3:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
So, Greatest Common Divisor of 662, 661, 402, 561 is 1
