Given numbers are 991, 245, 715, 807
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(991, 245) = 242795
GCD(991, 245) = ( 991 x 245 ) / 242795
= 991 / 245
= 991
Step2:
LCM(1, 715) = 715
GCD(1, 715) = ( 1 x 715 ) / 715
= 1 / 715
= 1
Step3:
LCM(1, 807) = 807
GCD(1, 807) = ( 1 x 807 ) / 807
= 1 / 807
= 1
So, Greatest Common Divisor of 991, 245, 715, 807 is 1
