Given numbers are 427, 854, 630, 661
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(427, 854) = 854
GCD(427, 854) = ( 427 x 854 ) / 854
= 427 / 854
= 427
Step2:
LCM(427, 630) = 38430
GCD(427, 630) = ( 427 x 630 ) / 38430
= 427 / 630
= 427
Step3:
LCM(7, 661) = 4627
GCD(7, 661) = ( 7 x 661 ) / 4627
= 7 / 661
= 7
So, Greatest Common Divisor of 427, 854, 630, 661 is 1
