Given numbers are 212, 226, 143, 647
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(212, 226) = 23956
GCD(212, 226) = ( 212 x 226 ) / 23956
= 212 / 226
= 212
Step2:
LCM(2, 143) = 286
GCD(2, 143) = ( 2 x 143 ) / 286
= 2 / 143
= 2
Step3:
LCM(1, 647) = 647
GCD(1, 647) = ( 1 x 647 ) / 647
= 1 / 647
= 1
So, Greatest Common Divisor of 212, 226, 143, 647 is 1
