Given numbers are 781, 670, 715, 763
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(781, 670) = 523270
GCD(781, 670) = ( 781 x 670 ) / 523270
= 781 / 670
= 781
Step2:
LCM(1, 715) = 715
GCD(1, 715) = ( 1 x 715 ) / 715
= 1 / 715
= 1
Step3:
LCM(1, 763) = 763
GCD(1, 763) = ( 1 x 763 ) / 763
= 1 / 763
= 1
So, Greatest Common Divisor of 781, 670, 715, 763 is 1
