Given numbers are 770, 781, 222, 785
The list of prime factors of all numbers are
Prime factors of 770 are 2 x 5 x 7 x 11
Prime factors of 781 are 11 x 71
Prime factors of 222 are 2 x 3 x 37
Prime factors of 785 are 5 x 157
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 770, 781, 222, 785
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 781) = 54670
GCD(770, 781) = ( 770 x 781 ) / 54670
= 770 / 781
= 770
Step2:
LCM(11, 222) = 2442
GCD(11, 222) = ( 11 x 222 ) / 2442
= 11 / 222
= 11
Step3:
LCM(1, 785) = 785
GCD(1, 785) = ( 1 x 785 ) / 785
= 1 / 785
= 1
So, Greatest Common Divisor of 770, 781, 222, 785 is 1
