The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 560, 700, 508, 661
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(560, 700) = 2800
GCD(560, 700) = ( 560 x 700 ) / 2800
= 560 / 700
= 560
Step2:
LCM(140, 508) = 17780
GCD(140, 508) = ( 140 x 508 ) / 17780
= 140 / 508
= 140
Step3:
LCM(4, 661) = 2644
GCD(4, 661) = ( 4 x 661 ) / 2644
= 4 / 661
= 4
So, Greatest Common Divisor of 560, 700, 508, 661 is 1
